i'm gonna go a-/b+...
i give the cowboys an a- because they addressed their main weakness last year, which was the secondary. the shitty cornerback play (especially terence newman and alan ball) was a huge problem. i thought the cowboys competed well in games, and they lost some games because the secondary was terrible. they finally added players who have good ball skills (no marty) with brandon carr via free agency, and morris claiborne via the draft...mike jenkins has showed he can make plays on the ball (no marty) back in 2009 in his pro bowl season, and even though he played poorly in 2010, he bounced back and played pretty well despite being injured for a good portion of the season last year. so...if carr, claiborne, and jenkins all play well this coming season, the cowboys could possibly turn their weakness into a strength.
on the other hand, i give the cowboys a b+ because i don't like the fact that they traded up and sent their 2nd round draft pick to the rams...honestly, i thought the cowboys were done addressing their cornerback needs with the carr signing, so i didn't think claiborne would be drafted by the cowboys, and other needs the cowboys have are interior offensive linemen as well as a 3-4 defensive end. with no longer possessing a 2nd round pick, i don't know if the cowboys will be able to select any quality interior offensive linemen or 3-4 defensive ends that they targeted.
with that said, jerry jones has made some questionable decisions, and i hope he made the right choice in this draft.
