I don't think we will take a corner because the difference between players is not that great in the top 15. But if Dallas thinks Rolle, et al are special players then they will make our defense better and we should take them.
I just see us badly needing DE, WR, LB, FS, and depth at OL, RB, and FB. More than anything we need a franchise QB, but there isn't one going to be available.
