I would do this, you give up a bunch of mediocre players for a top tier RB. And P.S. its LAdanian Tomlinson
But seriously, Ward is in a 3 way RBBC, FWP is a walking hospital trip, Hester is looking more and more like he may become the WR3 and #4 option (behind Olsen the TE) for the bears and Shockey is worth about the most from the side your giving up. If you have Sproles, hell even if you didn't, I say do this deal in a heartbeat.
*Scrubs* for a 1st Rounder? ummm yeah!!
