I first noticed it a few years ago when Domanick Goodman from UC wore him out all over the field - I believe Goodman was a sophomore or redshirt freshman at the time. I attended the Wisconsin game last year and Paul Hubbard abused him, not to mention LSU and USC in recent big matchups.
Personally, if I had my way and the players to follow actually declare, this would be my dream draft through the first 4 picks:
1. Vontae Davis CB Illinois
2a. Everette Brown OLB Florida State
2b. Demetrius Byrd WR LSU
3. Chip Vaughn S Wake Forest
Of those, Byrd and Vaughn are seniors. But with it, you add a legitimate #1 CB, and if Will Allen is re-signed or maybe a Chris Gamble brought in via FA, you can allow them to sit at the #2 CB spot (where Allen would excel in my opinion due to his lack of ball skills though he's exceptional in coverage); An WOLB who can truly replace Joey Porter - I think Moses will continue to be Roth's backup and Charlie Anderson is a spot player. Brown goes 6'4" 252lbs and can run. Byrd gives Pennington/Henne a true #1 WR target with some size at 6'2", and Chip Vaughn can probably play either FS or SS depening on what happens with Bell, Hill, and Jason Allen. Just my two cents as of right now - obviously subject to change based on who declares, draft order, bowl games, etc.
