Seems Wilson's draft prospects have fallen do a sub par season, so do Saints take a shot if he falls into 2nd/3rd round. His pocket presence seems to be really good. Plus he seems to be a good athlete (similar to Brees)
Could be a optimum situation where he sits for a few yrs until Brees' contract is up. Personally I don't see Brees playing past his current contract especially if he gets another ring.
