One interesting prospect is John Simon. He played DT as a freshman, but is far too undersized to play there at 6'2"/265 with short arms. He played DE and some LEO (DE/LB hybrid) at Ohio State last year out of necessity. This year he is ticketed to play base DE again......but really he is a 'tweener in the bad sense where he is not long enough to play DE at the next level, but not big enough to play DT. His future might lie at ILB in a 3-4 ala Tedy Bruschi or even Mike Vrabel (who played inside and out). He is kinda similar to Melvin Ingram in a sense I guess in that he is short with short arms but a helluva pass rusher who you can move everywhere. Not quite as athletic as Ingram but still athletic.......and Urban Meyer said the only other player with a work ethic as strong as Simon's that he's ever seen was Tim Tebow, so you know NFL people are gonna overdraft him based on his intangeables. Watching the guy play though you would think, "no way does this kid not go in the first three rounds"
I love Denard, but there is almost no chance he's a quarterback in the pros. His footwork is awful; to the point where it might not be correctable. He's also 5'10" or 5'11" and 190 lbs. He's a much better wide receiver prospect, having never caught a pass, than he is quarterback.
I think Star Lotulelei is going to be a top ten pick. Like Ndamukong Suh at this point in the process, he's on people's radar but not a lot of draftniks are talking about him as an elite prospect. He's not quite on Suh's level, but I think he's the best defensive tackle in the class and I see him missing on quite a few early 2013 lists.
Bark Mingo and Sam Montgomery are both great defensive line prospects. Michael Brockers owes both of them a big portion of his signing bonus.
