I remember seeing footage on him from junior college, and he looked like an overweight beast (no disrespect intended, he was just huge, not football athletically huge), and seemed a little sluggish. Seeing this footage of him at UofA, it looks like Saban's workout program has gotten him into unbelievable shape! He moves more like a normal sized DE or a big LB, not a 400 lb NT!
I was afraid all he would be able to do would be fill a couple of holes in the line, now I'm psyched that he can actually play football!
