Gruden's 'QB Camp' airs tonight

Those of you who have followed our discussion on the 2010 quarterback class should tune in to Jon Gruden's "QB Camp" special Thursday night on ESPN (7 p.m. ET).

Gruden spent time with four of the draft's top quarterbacks -- Sam Bradford, Jimmy Clausen, Colt McCoy and Tim Tebow. Gruden wrote his evaluations here, where you can also watch video of each player. Here are some excerpts:

Gruden on Bradford: "The guy he reminds me of talent-wise is Vinny Testaverde -- and maybe it's because they wear the same number. Testaverde was a No. 1 overall pick and I saw him play when he came out of the University of Miami. They both have the ability to get the ball out quickly with velocity and to throw on the move. Bradford has a similar stature and he had dominant results much like Testaverde did in college."

Gruden on McCoy: "I tried to watch as much Drew Brees film with McCoy as I could because their overall physical size is very similar (Brees is 6-0, 209 pounds; McCoy is 6-2, 210 pounds). Offensive guards in the NFL are 6-5 today and some of the defensive ends and tackles are also, so he's going to have to create passing lanes at times."

Gruden on Clausen: "When I look at quarterbacks and see how they play when they are tied or behind in the fourth quarter, that tells me a lot about them. Clausen excelled at crunch time. The statistics speak for themselves and he has shown dramatic improvement every year. He's a polished, confident kid and I like his upside. I think he's really going to work at it and continue to get stronger."

Gruden on Tebow: "I think Tebow is going to be a tremendous pro. He must continue to work on some of his mechanics, and he might not be a starter right away, but in a very short period of time he's going to be an excellent NFL player."
