This is an addendum to the Fantasy Football Preview published on Bullz-Eye.com.

The tough thing about publishing fantasy football rankings in early August is that the game is fluid and things are continually changing as injuries occur, depth charts are modified and camp battles won. In an effort to keep our readers on top of things, here are several players that are rising or falling as the training camps progress.

RISING

Chris Johnson, RB, Titans
Johnson says that he wants to be rookie of the year, so the kid has high aspirations. He’s slated right now to the “lightning” to LenDale White’s “thunder,” but White has never been one of Jeff Fisher’s favorites, so the team might just give Johnson as big of a role as he can handle. I doubt he takes over the job, but it sure looks like a RBBC is forming in Nashville.

Chris Perry, RB, Bengals
Perry has been having a strong preseason and, given Rudi Johnson’s lingering injury problems, he has been tentatively given the starting job. This could be a motivational tactic aimed towards Rudi, and Perry has had injury issues of his own throughout his career, but right now he looks like a nice gamble in the late-middle rounds.

Larry Johnson, RB, Chiefs
LJ has looked good thus far and seems to be back on track. The big question is if Brodie Croyle is capable of keeping opposing secondaries honest. With his foot looking like it’s completely healed, Johnson has become a solid pick in the early second round.

Phillip Rivers, QB, Chargers
Rivers reportedly looks terrific in camp and has improved his strength and reaction time. Now that Antonio Gates is back in action, Rivers has all of his weapons in place.

Ray Rice, RB, Ravens
Willis McGahee has a sore knee and his (lack of a) work ethic has him on the outs with the team. Rice has been a nice surprise in camp and could work his way into the starting role if the team decided to part ways with McGahee (or if he can’t go because of the knee). At the very least, he’s a must-handcuff for McGahee owners.

Wes Welker, WR, Patriots
That mysterious ailment that kept Welker out of practice turned out to be a groin injury. He says he’s 100%, so there’s no reason to think that he won’t be able to finish in the top 15 in PPR leagues. He’s a nice pick in the fourth round.

Ted Ginn, WR, Dolphins
Chad Pennington gives the team a bona fide NFL QB (though the team hasn’t given him the job yet), so look for Ginn and WR2 Derek Hagan to do a little better than we might have expected before the trade. Ginn is a second-year WR with a lot of talent, so he’s a breakout candidate and is an interesting pick once the rounds hit double digits.

Ricky Williams, RB, Dolphins
Williams has looked so good thus far that there were actually rumors that the team was thinking about moving the oft-injured Ronnie Brown before the season. The coaching staff has squashed that rumor, but it does look like Williams has earned a bigger than average role for a backup RB, and should be one of the first backups selected on draft day. He might even begin the season as a starter.

Michael Turner, RB, Falcons
“The Burner” has looked great in the preseason and some folks are thinking that maybe the Falcons’ running game won’t be that bad. The fact that Atlanta is likely to be playing from behind a majority of the time is still a concern, but Turner looks like he’s ready for prime time. I’d be happy to take him in the fourth round.

Nate Burleson, WR, Seahawks
Somebody has to catch passes in Seattle, and right now Burleson is the best the Seahawks have. He’s been a fantasy tease for a few years now, but he’s an interesting pick in the late-middle rounds.

Jonathan Stewart, RB, Panthers
Stewart appears to be healthy and will get an opportunity to run with the first team in the Panthers’ next preseason game. The team is clearly down on DeAngelo Williams, so if Stewart can get his power game going, he may be the main back early in the season.

Antonio Gates, TE, Chargers
Gates has finally been cleared to return to practice, so he should be good to go for week 1. This news solidifies his standing in that top tier of TEs along with Jason Witten, Tony Gonzalez and Kellen Winslow.

Steve Slaton, RB, Texans
The feature back job in Houston is up for grabs, and Slaton has been the most impressive thus far in camp. Ahman Green is hurt and Chris Brown will probably assume the #1 role until he gets injured. Slaton is probably too small for full time duty in the NFL, but he could turn into a decent spot starter, which isn’t bad for a guy available late in fantasy drafts.

FALLING

Bobby Engram, WR, Seahawks
Engram has a shoulder injury that is going to keep him out until at least week 5. He has gone from a savvy pick in the 8th round, to a savvy pick in the 11th or 12th. Remember, he’s 35, so there’s no guarantee that he is going to heal quickly.

Peyton Manning, QB, Colts
Manning still is sidelined with a knee injury and the team is saying that they hope to have him back for the season opener. I wouldn’t get too worried about Peyton, but I wouldn’t take him in the second round either. Tony Romo and Drew Brees are safer bets right now at QB.

Rudi Johnson, RB, Bengals
Johnson has been battling a sore hamstring. As a result, he has lost his starting job and has gone from an interesting mid-round pick to a late round flier.

Matt Hasselbeck, QB, Seahawks
He lost Bobby Engram to injury and now he has a sore back. Hass is still worth a pick in the 8th or 9th, but I’d much rather have Jay Cutler or Donovan McNabb.

Ronnie Brown, RB, Dolphins
Brown is recovering from knee surgery and now has an injured thumb. To make matters worse, Ricky Williams is looking good, so it seems like Brown could open the season as a backup. That makes his fourth-round ADP look ridiculous.

Willis McGahee, RB, Ravens
Head coach John Harbaugh says that McGahee is the starter when he’s ready to go, but the rumblings from Baltimore paint a bleaker picture. They say that McGahee’s poor work ethic has him in the doghouse and Ray Rice keeps vying for the starting job. I’d still grab McGahee in the fourth, but only after guys like Brandon Jacobs, Earnest Graham and Thomas Jones are off the board.

Chad Johnson, WR, Bengals
It’s all about the dislocated shoulder. The team says he’ll be fine, but they also indicated that the injury was a big part of the decision to re-sign Chris Henry. Johnson should be okay, but I don’t think I’d draft him before Plaxico Burress, Wes Welker or Anquan Boldin until we know he’s good to go.

Kevin Curtis, WR, Eagles
Curtis is going to miss about half the season with a sports hernia injury. Obviously, his stock should take a huge hit, and he isn’t worth anything but a late-round flier with the thinking that he might be back to help during the late-season push.

Ahman Green, RB, Texans
I thought this was a horrible contract when the Texans first signed Green and now it looks even worse. Green is hurt again and he might just get cut if he can’t get it together. Stay away, stay far away.
