I like DRC and have always believed him to be one of the two most intriguing players at CB; Leodis McKelvin was the other guy. I also believe that he is more talented than Aqib Talib, who is extremely inconsistent and seriously need to work on fundamentals. That said, at this point, I would not want either player at #10. I think if Dorsey or Ellis are gone, you start to look at a guy like Keith Rivers assuming no other top payer has fallen lower than expected.
Talib is not the answer, though. Heck, I would not touch him in the first round even though I know he'll be taken in the first. I would much rather have a guy like Tracy Porter in the second than Talib anywhere in the first as I think he's a boom/bust type player.
