I am coming around on Williams. I'm now sold on the fact that his slowness off the ball is because of UGA's scheme - I started watching his cutups for the half dozen times per game where he had the green light to floor it, and he's about as fast as a 265 lb man gets. It's not a Mazi situation where that explosion just isn't there.
So I think the pass rush potential is there, and he's got great run stops all over his tape. That part of his game is undeniable. I'd give him the green light at #12.
I agree with the doubters on Jalon Walker. Doesn't have the instincts to play full-time LB and only offers speed as a pass rusher. You still take him 1st round because of his rare speed, but I damn sure wouldn't take him at #12. There's at least 5 other DEs I'd rather have.
