45. Darrelle Revis
Most Dominant Year: 2011
Best man cover corner in the NFL. Takes away a full side of the field. Supreme technician. You'd think Revis would be higher on this list, right? Yeah, but like Asomugha, he suffers from the fact that smart gamers rarely throw to their outside receivers. He's still a heckuva player, though, and here's an idea: Play him at strong safety so he can cover those tricky slot wideouts.
