Trade Help re: Brady

12 man, PPR

I've had really bad QB luck this season. Over the last 5 weeks, only once have I had a QB play all 4 quarters (Vick, Cutler, Pryor, Locker, and Keenum were my last 5 starters). Despite that, I'm still 7-4, but am trying to make up a move to shore up my QB spot.

My team:

QB: Keenum
RB: Reggie Bush
RB: Frank Gore
WR: VJax
WR: Steve Smith
TE: Gates
FLEX: Bowe

Bench:
Ray Rice
James Jones
De'Andre Hopkins
Michael Crabtree
Brian Leonard

The proposed trade I am considering is Ray Rice, James Jones, and Case Keenum for Brady, Jacoby Jones, and Kenbrell Thompkins. Thompkins and Jacoby are throwaways, and I will most likely cut them. The guy I'm trading with is eliminated from the playoffs, but still wanted to take a deal that he would make if still competing, which is fair. This deal would leave me thin, but being that it's almost playoff time I feel like I need to go all in and get legit QB. What do you all think?
