After all the Twitter hype around quarterback hand sizes, the real business of evaluating the college quarterbacks has started at the NFL combine. This position dominates draft discussions, as the concept of “best player available” really doesn’t apply to the quarterbacks versus other positions. Teams that need a quarterback have a much different approach in the first round versus teams already set at the position.

This year there are three guys everyone sees at the top of the QB class, but further scrutiny is starting to affect how each of them are perceived. Here’s Pat Kirwin, one of the best commentators in the business, on what he is seeing so far.

We all arrived in Indianapolis believing there were three quarterbacks set for the top five picks. However, one GM said, “I’m glad I don’t need a franchise QB this year. … too many questions [are] starting to surface on this group.”

An example: Teddy Bridgewater told me Saturday he was going to run but never did. The same GM said of Bridgewater: “He beefed up to 214 to appear bigger, but he better not think he can drop the weight to run at his pro day. We don’t fall for that one.”

Johnny Manziel is 5-foot-11 3/4, not 6-foot as he had been listed. One coach told me “[Manziel] keeps trying to portray the image of the next Russell Wilson and I’m not buying it.”

I liked Bortles the best of the three, but time will tell if the teams at the top of the draft think so. I left Indianapolis with the impression that the real QB work was about which guy to take in the second or third round.

He makes the point that many teams are taking a hard look at the offensive tackles and that these players are moving up draft boards. That position seems to offer much less risk at the top of the draft, and guys like Jake Matthews, Greg Robinson, Taylor Lewan and Zach Martin have been impressive at the combine. Robinson in particular stunned with his 40 time.

It’s still early, but this year predicting the order of the top ten seems particularly difficult, and so it will be hard to predict the QB decisions that will affect teams for next year. So if you like betting NFL futures when you use your Bet365 offer code, keep in mind that the odds can change dramatically once these QB decisions play out.

Houston in particular is a tough one to predict. A pro-ready quarterback like Teddy Bridgewater could make them a playoff team again overnight. Opinions on Johnny Manziel vary dramatically, but if he thrives in the NFL he could turn around a team like Houston very quickly. Meanwhile, Bortles might be the best pick in terms of long-term potential, but he’s a real project. Unless Houston gets a good veteran to play in front of him, they would likely struggle with Bortles starting right away as he has so much to learn.

On the other hand, they could draft Jadeveon Clowney as a bookend to JJ WAtt on that defense, and all of a sudden they could be dominant on that side of the ball again. Give them a veteran QB and you suddenly have a real team again.

So good luck making picks at this stage of the game.

Should Brady Hoke still get a pass as he tries to undo the damage Rich Rodriguez did to the Michigan program? Or should he be help accountable for the mess we’re still seeing in Ann Arbor?

Michigan fans are losing patience, though Big Ten fans are also getting frustrated. Sure, as an Ohio State fan, it’s always fun to watch the Buckeyes stomp Michigan, and that has become a regular occurrence in the past 15 years. But the strength of the conference is seriously compromised when Michigan consistently plays like Purdue. Beating Michigan becomes an afterthought as opposed to a quality win that impresses around the country.

Jason Whitlock is a friend of Hoke’s, and he believes that Hoke will ultimately be successful at Michigan, but he has some harsh words for what’s going on now with the programs.

Brady Hoke, lost in the riches of Michigan, has momentarily lost who he is.

Hoke walked on at Ball State. No one wanted him. He turned himself into a starting linebacker on the 1978 Ball State team that finished 10-1. He was the captain of the 1980 squad.

As coach at Ball State, he didn’t have an office. The school barely supported the football program. He took a bunch of kids few programs wanted, won a dozen games, and produced a crop of players that included three NFL offensive linemen, an NFL tight end, an NFL quarterback, and a receiver who would’ve played in the league if not for a neck injury. At San Diego State, he did the exact same thing, and the Aztecs didn’t even have their own stadium.

Brady Hoke is an underdog. He has an attitude, a chip. He’s self-made. He always has something to prove. It’s one of the reasons he connects with Tom Brady, a kid Hoke recruited to Michigan, a QB who plays with a massive chip in the NFL.

For three straight years, Hoke has been a recruiting star, landing high-profile recruits from all across the country, swiping talent from Ohio State and other blue-chip programs. Hoke might get the No. 1 class in 2014.

He’s five-star struck. On the recruiting trail, he has sacrificed character, grit and maturity for ratings stars. His top recruit in 2013, freshman running back Derrick Green, reported to camp 20 pounds overweight. Green is soft. On Saturday, the 245-pounder dove at the ankles of a blitzing linebacker and whiffed. Green barely plays.

He goes on to rip other Michigan recruits from the Hoke era along with stars on the team like Taylor Lewan who he accuses of “coasting.” I have no idea whether Whitlock is right here. He may be going too easy on his friend and taking out his frustrations on the players. Would Urban Meyer be having these problems?

Bob Wojnowski is harsher when evaluating Hoke, blaming the problems at Michigan on “poor coaching.”

Hoke came to town with some bluster and bravado, refusing to call “Ohio State” by its proper name bu instead just saying “Ohio.” Perhaps he should focus more on fundamentals as opposed to making waves at press conferences. In the end, the losses with drown out everything else.
