I really don't think they should. The problem problem looks to be a slow start by Favre. They should be able to cobble something decent with the talent on the roster and ADP.
The problem, IMO, is that Favre doesn't trust any receiver other than Harvin and Shaincoe.. Teams are doubling up on Shiancoe and Harvin isn't 100% and isn't practicing enough to get "in sync" with Favre.
Get VJ, who can out leap 90% of CB's and Favre has a target he can trust to go up and get the ball.
I say they make a move an get him.. If they have any shot at the Super Bowl this is the last year for a couple years IMO.
Favre is done, Pat Williams is done, Winfield is aging, the OL needs to be rebuilt as Load"ofcrap" and Mckinnie are just not cutting it, QB is a BIG question mark after this year...
Giving up a 2nd rounder for VJ is worth it as a "last chance"..
