Defensive line

Overrated: Kentwan Balmer, North Carolina

I'd like to think I follow college football fairly closely, so what I'm about to admit may seem a tad bit embarrassing: I had literally never heard of this guy prior to this week. So you can imagine my surprise when I saw him smack dab in Peter King's first-round Mock Draft. Either I need to start watching more ACC football (which itself may require a steady IV drip) or there's a legit reason I'd never heard of him: The fact that he did almost nothing to distinguish himself his first three seasons. He did have a big senior season, earning all-conference honors, but mostly, he's just big (6-4 1/2, 308 pounds).

Underrated: Quentin Groves, Auburn

Groves was limited by injuries at times last season, but when he was at his best, he was definitely one of those guys who can take over a game just by the pressure he puts on opposing quarterbacks. He did just that in the Tigers' early-season upset at Florida, helping limit Heisman winner Tim Tebow to mostly short completions. The year before, when fully healthy, he notched 9.5 sacks. The only defensive end I'd rank above him is Chris Long, and if, as projected, Groves slips into the second round, someone is going to get themselves an absolute steal.
