I think Perkins has been a forgotten player in this draft, and will be a good returner, no doubt. 3rd round is probably right, and Dallas won't have a shot in the third round unless they trade down. Perkins is magical in the return game, but Parcells pet project is to get small school return guys on the cheap. Picking a 3rd round pick that's almost exclusively a return guy (I've seen him play) is not a Parcells move.
However, Josh Bullocks as a free safety in the second is just too perfect a match. His talent level is definitely round 2, and is the closest thing to Ed Reed, except for maybe Antrelle Rolle, and Dallas needs to draft a pass rush first. Then FS next priority in my mind.
