Other than the obvious offensive line that needs to be addressed I think the conerback posistion is a real weakness. I think the Cards should push really hard for Nate Clements. Their other target at conerback should be Nick Harper. If you could land either one they should start opposite Eric Green. Antrel Rolle should either be traded or moved to safety he is a terrible conerback and still can't understand why Green is benched and Rolle isn't.
They also need help at linebacker and should make a push for AdaliusThomas, Lance Briggs or Cato June. Hopefully they haven't blown it with Dansby and can extend his contract. With either of those three, Dansby , and Hayes there is a good LB group.
The second pick will be good enough to get Joe Thomas in the draft, so they should resign Davis move him to G and start Thomas at LT. I would send Orlando Huff and Chike Okeafor packing and take a DE with the second round pick.
In never did like Rolle as a 1st Rd pick to start with. He has always been to slow and you cannot teach speed. He can still learn as he sat out most of last year but speed will always be a problem for him in man to man. Seems to me that there are as many good DB's playing in the NFL who were not top draft picks as those who were. DB's on good teams in college get a lot of hype often undeserved as they are playing behind great defensive lines. Unless there is clear great DB like Deion Sanders I would move this pick down to 3 or 4 as it is always a big gamble. Currently Rolle really sucks and teams will continue to throw at him.
