Clayton: Potential cap casualties,all 32 teams Cap situations*

Can someone please explain to me why Philly is rumored to be so interested in Reggie Bush? I don't understand why they would want or need him when they have 2 RBs similar to him already, and Desean Jackson returning punts.

I could honestly see Tampa being the team that gives Reggie an offer he can't refuse... if he does get released.
