If we target a CB I personally feel we should move back into the 20's. IMHO Gilbert is the best but not exceptionally better and you can take Dennard, Fuller, and Roby are whatever your flavor is. All ranked pretty much the same to me.
The guy I like is Stanley Jean-Baptiste. 6-3 218lbs 4.45-4.55 forty. Then even later round guys are EJ Gaines, Ricardo Allen, and Louchiez Purifoy for 4th or later guys. In my opinion the difference between EJ Gaines and Dennard is minimal.
Ford, the guy that I have liked since the East-West game is Cockrell. I didn't watch much of him but in the Fla. St game I thought he played very well against Benjamin. Considering they got blown out he however played well. It looks like they switch from zone to man so I would say he can play both systems and he has good hands. There are a few things I didn't like about him and they are he got blocked to easy and he was very poor at tackling.
I like the guys you mentioned and Allen had a nice East-West game as well. After watching the video in the other thread about Fuller I am liking him at 15. If we do take a cb at 15 I am wondering if there is a chance we grab one of the guys you mentioned later in the draft?
I like Cockrell but I feel he might be limited physically. Allen also is physically limited but he has return skills which increases his value. I personally don't go CB in one just because no one blows my squirt up out of the "top" guys. I'd rather take Jean-Baptiste in the second then double back later and get another CB later. Same with receiver unless Watkins or Evans are there I'd trade back or draft one later.
