Two tackles:
OT Doug Free ~ Northern Illinois -- It's no surprise NIU's offense has been so productive recently, when you consider the caliber of offensive lineman they have put on the field. Free, without a doubt, is the best OL prospect this school has produced in a long time. A very athletic and nimble 6' 6", 305 pounder, who plays the game with intensity. Might be the best prospect in MAC and likely day 1 pick.
OT Joseph Staley ~ Central Michigan -- Staley, a high school tight end and track star, has been on the radar of NFL teams due to his unique athletic skills for a man his size: Ran a 4.7 40 at 6' 5" and 300 pounds at CMU's Pro Day. Improving as a lineman. May not be as highly regarded as Doug Free right now, but Staley is a player to watch.
