One month ago I had a lot of debate as to who is the best pound-for-pound fighter in the world.

After UFC 101, my questions were answered.

Long have I felt Fedor Emelianenko was the best in the world no matter the weight class, but that honor I now give to Anderson Silva following his absolutely flawless win over Forrest Griffin.

The Silva victory combined with Emelianenko opting to sign with Strikeforce puts Silva at No.1 in my book. When making this list I am considering the fighters as they are today, not as they were five years ago. Emelianenko looked a little sloppy in his last fight and is now going to have much easier competition as a whole in Strikeforce, whereas Silva and Georges St. Pierre have fought the best and looked impressive doing so.
So, here is my list. As always, I encourage healthy discussions.

1. Anderson Silva (24-4) – Middleweight/Light Heavyweight – UFC
If you really look at, the Silva vs. Griffin fight was every bit as big as St. Pierre vs. Penn from a standpoint that you had a champion from one weight class facing a bigger fighter that was one fight removed from being the champion in that weight class as well. Silva made Griffin look like Glass Joe from Mike Tyson Punch Out and basically made Griffin quit out of embarrassment (which has caused me to stop reading Forrest’s book, as he know seems to look like a hypocrite). After that display, I truly feel that Silva could not only be Light Heavyweight champion, I have serious beliefs that he is the kind of guy that could actually beat a guy like Brock Lesnar. His accuracy and power while backing up would be a problem for Lesnar in more ways than one. Brock wouldn’t be able to get a takedown without eating a solid knee or punch that could put him down. I know many of you think I am crazy probably, but that is the way I feel.

2. Georges St. Pierre (19-2) – Welterweight – UFC
I used to think GSP could give Silva a fight, but I don’t feel so good about that now. If Silva was to move to Light Heavyweight on a permanent basis, I would like to see GSP move up to middleweight for a new set of challenges. Guys like Mike Swick and Martin Kampmann don’t seem to present much of a challenge and nobody is going to be excited to see rematches with Jon Fitch or Thiago Alves. Middleweight could present some intriguing fights and would really test GSP.

3. Fedor Emelianenko (30-1-1) – Heavyweight – Strikeforce
Well, again this is all about present day and Fedor hasn’t done anything as of late to keep his top ranking while guys like Silva and St. Pierre are beating some of the best. Fedor had no control over what happened with Affliction: Trilogy, but the option to sign with the UFC was there and he turned it down. He has to know that UFC has better overall talent and hosting an exhibition sparring match with Gegard Mousasi is not going to get me excited. I think Fedor’s career is probably the best of anyone, but in terms of best fighter in the world today, I don’t see him as No. 1.

4. Lyoto Machida (15-0) – Light Heavyweight – UFC
Machida is on his way to building an argument for the No. 1 spot after his quick finishes of Thiago Silva and Rashad Evans. Machida has a unique style like Anderson Silva that has been hard for opponents to figure out. Machida vs. A. Silva is the fight people would love to see, but alas, it will not happen as both have stated they won’t fight each other due to their close bond. Machida is another fighter that seems to be able to transcend his weight class and I think could pose a great challenge to the heavyweight division.

5. Brock Lesnar (4-1) – Heavyweight – UFC
People hated the idea of Lesnar being on this list, but which fighter in the heavyweight division has looked better than him in the last couple years. Lesnar disposed of Randy Couture and Frank Mir and dominated Heath Herring. His speed, power, and agility are equal to any smaller-weight fighter, but he applies it all to a 285-pound frame. Lesnar is still learning but has clearly looked better in his last three fights than other heavyweights like Couture, Mir, Nogueira, CroCop, and Arlovski. Other up and comers like Shane Carwin, Cain Velasquez, and Brett Rogers still have to sustain wins over big names to surpass Brock.

6. BJ Penn (14-5-1) – Lightweight – UFC
Penn showed why he is the best lightweight in the world with his submission win over Kenny Florian at UFC 101. Diego Sanchez in up next for Penn, but I still feel the Hawaiian would rather be fighting at 170, where he thinks he can be the best there too. Perhaps with a few more wins at 155, Penn can take another crack at the 170-pound weight class.

7. Jake Shields (23-4-1) – Welterweight/Middleweight – Strikeforce
Shields is another fighter that has had success in multiple weight classes, but he is not higher on the list because his competition is not as deep as other fighters. I think Shields could be a great challenge for St. Pierre in the UFC, but for now he is set at Strikeforce, where the organization seems locked into to making him their marquee fighter.

8. Mike Thomas Brown (22-4) – Featherweight – WEC
Not much new on Brown, but he does have an upcoming fight with Jose Aldo, which may be a tougher fight than his two with Urijah Faber. Aldo is explosive, but a win for Brown would push him higher up the list.

9. Miguel Angel Torres (36-2) – Bantamweight – WEC
I know many will cry foul here, but I am not going to write off Torres. His loss to Brian Bowles was clear cut, but Torres had Bowles hurt prior to getting caught. I still look at Torres and see him as the best 135-pounder in the world. Bowles will have a chance to show the win was no fluke in the near future, but for now, I look at this loss like St. Pierre’s loss to Matt Serra. We all know then that Serra was not the best in the world, and I don’t see Bowles as the best yet either.

10. Rashad Evans (13-1-1) – Light Heavyweight – UFC
Rampage Jackson held this spot a month ago, but based of Griffin’s loss at UFC 101, I think that hurt Jackson’s stock, as he was unable to really damage Griffin much in their fight last summer. Evans made shorter work of Griffin and seems to be more of a multi-dimensional fighter than Rampage, who hasn’t changed up his game much over the years. When Evans and Rampage fight in December, that will answer the questions as to who should be in this final spot.

Honorable Mention: Thiago Alves, Rampage Jackson, Dan Henderson, Gegard Mousasi, Jon Fitch, Shinya Aoki, Diego Sanchez

- On a side note, give me Gina Carano in an upset and Mousasi in a quick win at tonight’s Strikeforce card.

At one point following UFC 100 this past weekend, I felt like there are a lot of new questions about who the best pound-for-pound fighter in the world is.

Georges St. Pierre certainly raised his stock with a definitive win over Thiago Alves, who was considered to be GSP’s toughest fight to date prior to UFC 100.

Brock Lesnar also deserves some consideration for his dominant performance over Frank Mir, which left many wondering who can beat him.

Here is my personalized top 10 ranking of who I feel are the top 10 overall fighters in the world. In making this list, I consider win-loss record, how convincingly the fighters have won their most recent fights, and their appeal to other fans. Well, here we go:

1. Fedor Emelianeko (30-1-1) – Heavyweight – Affliction
About a year ago, I was one of those people that claimed that Fedor was overrated and didn’t fight the best. Well, after two quick KO’s of Tim Sylvia and Andrei Arlovski, you can’t argue that Fedor is not the best. The guy has virtually never lost, with his lone loss coming on a cut. The guy never changes his expression and never makes a mistake in his fights. Until someone beats him cleanly, Fedor will be at the top of my list.

T2. Anderson Silva (23-4) – Middleweight – UFC/ Georges St. Pierre (19-2) – Welterweight – UFC
I have Silva and GSP tied because of pure dominance in their weight class. As of late, Silva has not looked his usual self in his last two fights, but part of that is because his opponents have tried to avoid his lethal strikes. GSP has been dominant in another way, controlling his opponents four as long as it takes to win. GSP has fought the tougher competition as of late, but Silva has tougher fights in his future than GSP with Dan Henderson, Damian Maia, and Nate Marquardt looming while GSP has significantly less talented fighters like Mike Swick and Martin Kampmann to deal with. A super fight between these two is appealing, but it seems like GSP is hesitant to move up in weight right now.

4. Lyoto Machida (15-0) – Light Heavyweight – UFC
Machida is unbeaten which certainly earns credibility, but in his last two fights, he has quickly finished two of the top Light Heavyweights in the world. Machida takes little to no damage in his fights and has pin-point accuracy in his strikes along with a sound jiu-jitsu game. It is tough to think of a fighter that will be able to disrupt Machida’s style, but Shogun Rua will try at UFC 104.

5. Miguel Angel Torres (36-1) – Bantamweight – WEC
It is a shame that not many know about Miguel Torres because he fights in the lesser-known WEC. But, if more fans saw Torres compete, there would be more MMA fans than ever. Torres is complete in every way and is the one fighter I can say leaves everything he has in the cage with each fight. His pacing is incredible and his diverse strikes make him one of the most entertaining fighters in the world. Torres may soon have to face the option of moving up in weight to set up potential super-fights with some of the other WEC’s top stars.

6. Brock Lesnar (4-1) – Heavyweight – UFC
I don’t like Lesnar, I think his attitude and approach to “entertaining” the fans is awful, but I can’t deny his natural ability. He has destroyed Heath Herring, Randy Couture, and Frank Mir in successive order, and he is just five fights into his professional career. As time moves on, Lesnar is only going to improve and get better in each area of fighting, which is a scary thought for every heavyweight. A fight with Fedor is the talk of the town right now, but I think Lesnar would be biting off more than he can chew with that right now. In another year or too, he certainly could dethrone “The Last Emperor”.

7. BJ Penn (13-5-1) – Lightweight – UFC
I also am not a fan of BJ Penn for his attitude on his opponents, but I also can’t deny his natural skills either. Penn’s flexibility is something no other fighter posses right now and is the reason he is considered one of the best in the world in any weight class. Penn’s record is not as strong as most, but his losses are deceiving, as he has fought many bigger fighters and given up 30 pounds or more in those fights. Losses to fighters like Machida should almost be ignored. As a lightweight, it is tough to think anyone can compete with Penn, let alone beat him.

8. Jake Shields (23-4-1) – Welterweight – Strikeforce
Shields is as hot as any fighter, winning his last 12, including his most recent win over Robbie Lawler in a bigger weight class. Shields is one of the best submission and grappling fighters in the world and many believe he could give Georges St. Pierre a run for his money.

9. Mike Thomas Brown (22-4) – Featherweight – WEC
Brown proved his worthiness to be WEC champion with a second win over Urijah Faber. Brown is a sound fighter that can stand on his feet and control on the ground. He may not be flashy, but he is dangerous anywhere in a fight and his level-headed attitude makes him a dangerous fighter.

10. Quinton Jackson (30-7) – Light Heavyweight – UFC
Jackson has beaten some of the best in the world, but his split-decision loss to Forrest Griffin set him back. You could argue that Jackson didn’t lose to Griffin and could still be UFC champion, but he hasn’t backed off, beating Wanderlei Silva and Keith Jardine since losing the belt. Next up is Rashad Evans and a win there gives him a title shot that he should have had a lot sooner.

Honorable Mention: Thiago Alves, Rashad Evans, Dan Henderson, Urijah Faber, Jon Fitch, Kenny Florian, Shinya Aoki, Nick Diaz.

Mike Brown’s rematch with Urijah Faber is tonight at 9 PM ET on VERSUS. In preparation, be sure to check out Drew Ellis’s in-depth interview with Brown, as well as Drew’s preview of WEC 41. (Scroll down, you’ll see it.)

This weekend Mixed Martial Arts has two solid shows taking place outside of the UFC label. It begins Saturday on Showtime at 10 p.m. with Strikeforce presenting a strong card of recognizable fighters, a few of which are still considered among the best in the world. On Sunday, the WEC (World Extreme Cagefighting) takes center state with WEC 41: Brown vs. Faber 2, which is highlighted by the Featherweight championship (145 lbs) rematch of champion Mike Thomas Brown against former champion Urijah Faber. That show will air on Versus at 9 p.m.

Here is a quick breakdown of the feature fights and my predictions for both shows:

Strikeforce at the Scottrade Center in St. Louis, Mo.

- Kevin Randleman (17-12) vs. Mike Whitehead (23-6) Light-Heavyweight (205lbs): Kevin Randleman was a giant in the MMA world in the late 90’s and in the beginning of the 2000’s, but now Randleman is finding himself in the same position as many of the giants in those days like Ken Shamrock and Royce Gracie, where the sport has passed him bye. Loser of five of his last seven fights, Randleman needs a win over UFC veteran Mike Whitehead, who has won 13 of his last 14 and has looked good since his move down to light-heavyweight (205 lbs). I like Whitehead by decision or TKO from ground-and-pound on a tired Randleman.

- Joe Riggs (29-10) vs. Phil Baroni (13-10) Middleweight (185lbs): Phil Baroni and Joe Riggs are classic examples of two fighters that had worlds of potential and never tapped into it. Both men have tremendous power, but both are notorious for their lack of endurance as fights move on. Baroni tries to throw all his power in each punch which limits him later on and Riggs has a suspect chin that has caused quick knockout losses. If Baroni has truly improved his training, I see him winning this one as Riggs is the mentally weaker fighter. I take Baroni by TKO late in round one.

- Andrei Arlovski (15-6) vs. Brett Rogers (9-0) Heavyweight (265lbs): Arlovski in my opinion is the second best heavyweight in the world who took a tough loss to unbeaten Fedor in the last Affliction PPV. Prior to the knockout, Arlovski was winning the fight with the pound-for-pound king, but a poor choice to go for a flying knee setup the loss. Now, Arlovski looks to rebound against Brett Rogers, who has won all nine of his pro fights in dominant fashion, but has never faced a test like this. I see Arlovski winning by TKO in round two.

- Nick Diaz (19-7) vs. Scott Smith (15-5) Middleweight (185lbs): Nick Diaz has been one of the most confusing fighters in MMA. Diaz holds wins over some of the world’s best like Robbie Lawler and Takanori Gomi, but has also lost to sub-par competition like Joe Riggs and Jeremy Jackson. Recently, Diaz had an emphatic win over Frank Shamrock and a win over Smith would put him in the sights of a rematch with Lawler, who he knocked out at UFC 47 in one of the biggest upsets in the sports history at the time. Smith is certainly a game fighter that can KO anyone with one shot, but Diaz should outclass him and dominate the fight. I see Diaz by submission in round three.

- Robbie Lawler (16-4) vs. Jake Shields (22-4-1) Catch-weight (182lbs): The fight will take place at a catch-weight of 182 lbs with Shields making the move up from welterweight (170 lbs). Lawler is considered by some as the No. 2 middleweight in the world and has not lost in his last six fights. His most recent win is over Scott Smith in Elite XC before the company went belly up. Shields, who was the Elite XC welterweight champion has won his last 11 fights but is making his first climb into a bigger weight. I feel Shields is the better all-around fighter, but in the end, the weight change will play into Lawler’s favor. I see Lawler by TKO early in round three.

WEC 41: Brown vs. Faber 2 at the Arco Arena in Sacramento, Calif.

- Josh Grispi (12-1) vs. Jens Pulver (22-11-1) Featherweight (145lbs): Jens Pulver was the first ever UFC lightweight champion at 155 lbs, but now Pulver finds himself at a crossroads. Pulver has lost five of his last six fights, including two to Faber in the WEC. Another loss may force one of the faces of MMA into retirement. Grispi has won his eight fights, seven by stoppage, including his last two which were in the WEC. A win for Grispi puts him in title consideration at 145 lbs. I like Grispi to take an older, slower Pulver by TKO in round one.

- James Krause (10-0) vs. Donald Cerrone (9-1) Lightweight (155lbs): Cerrone is coming off a razor-thin split decision loss to WEC champion Jamie Varner and many still consider him the best 155-pounder in the WEC. A win for Cerrone would certainly set-up a rematch with Varner for the title. Krause is making his WEC debut with a perfect record, but this will be his toughest opponent to date. I like Cerrone with his big-fight experience by submission in round one.

- Jose Aldo (14-1) vs. Cub Swanson (13-2) Featherweight (145lbs): Aldo is the hot name in the WEC right now as he has won all four televised bouts by KO or TKO. Aldo is in line to face the Brown-Faber winner with a win over Cub Swanson, who has rebounded with back-to-back wins after losing to Pulver in 35 seconds in December of 2007. Swanson is a good fighter, but I think Aldo has the momentum right now and the better stand-up, which will be the deciding factor. Give me Aldo by TKO from strikes in round two.

- WEC Featherweight Champion Mike Thomas Brown (22-2) vs. Urijah Faber (22-2): Rarely do you get to see a fight where there is a fairly unanimous feel that the two fighting are respectively ranked as the No. 1 and No. 2 fighter in the world in their weight class. Brown may have shocked the world in the first fight, winning by TKO in the first round over Faber, who was thought to be unbeatable, but Brown has since solidified his spot with his dominant win over Leonard Garcia in Garcia’s backyard of Texas. Faber bounced back from his loss to Brown with a quick submission of Pulver back in January and is hungry for payback. This fight should be as good as advertised with Faber’s full attention on Brown, and Brown eager to cement his legacy in the sport. Brown is a tremendous all-around fighter that is technically sound, while Faber relies on his athleticism, speed, and flexibility to utilize unorthodox strikes. Brown capitalized on a Faber mistake in the first fight and I see Faber fighting a smarter fight this time around, but if Brown can control the pace and win the opening rounds, Faber will get desperate and make a drastic move that will either win him his title back, or cost him another loss. I like Brown making the most of the mistake again and winning by TKO in round three. I can also see this being a 5-round war, but I will stick with my first choice.

Hope everyone gets a chance to sit down this weekend and enjoy some great MMA action.
