I like Don Banks, but...

I would love for us to move up for Revis. Unfourtantly Banks (correctly probably) has Revis going 15-20 and would be pricey for us to move up and get. It would take at least a 2nd and a 4th, probably a 2nd and a 3rd, to secure Revis. That's awfully expensive.

Considering who he has available, I think either Beason or Timmons would be solid picks. Both have potential as a WLB and MLB in the Saints scheme and give us some secruity/flexibility concerning Brian Simmons age. Plus I doubt any of us are sold on Shanle as a starter at WLB for the next 4 years. I like that they resigned him and am comfortable with him starting there next season, but he could be upgraded.

Also of interest would be Anthony Spencer (situational pass rusher/secruity for Charles Grant)

Given that position i'd love the Saints to trade down but i'm not sure how much value that position would have for anyone.

I would expect the Saints to attempt to trade up for either Hall or Revis if one of them fell to #16 or below.
According to one of the trade value charts I saw, our first and second picks would give us the ammo to trade up to #16.
If they were unavailable we would have identified trade partners from #17 to #26 to grab one of the other top CB's Houston, Ross or McCauley, if available.
Another option would be to move Charles Grant, although a draft day trade would not get us full value for him without a long term deal in place between him and another team. His $8M dollar cap hit would also be prohibitive unless the other team had a deal in mind that they'd be sure he would go for.
The next most likely position is WR with Meacham, Bowe, Ginn and Rice although with the current state of the roster I cannot see them not grabbing a CB with their first pick.
