I agree with this list, but I'd add:
13. Kendall Langford - He's an excellent 3-4 End.
14. Jimmy Wilson - I know he's a rookie and got beat yesterday, but he's going to be a player.
15. Roberto Wallace - He's going to be a starter some day.
16. Brandon Fields - I think you overlooked him because he is special teams, but he's probably the best punter in the league.
Now examining this list, the biggest dearth of talent appears to be the Offensive Line, followed closely by Tight End, Defensive Back and Linebacker.
U r absolutely right
regarding Brandon fields, the others u mention have a bit more to prove I think
