Should I trade for Derrick Lee?

Seems like he hasn't been the same since the wrist injury, but I can afford to take a chance. I'd probably offer Hideki Matsui and Jared Weaver for him. It's a 13-team keeper league. My staff is Sabathia, Bonderman, Verlander, Weaver, Colon. I've also got Randy Wolf, Jorge Sosa, Matt Morris, with Pedro stashed on the DL. My OF's are Carlos Lee, Rios, Ibanez, Matsui and Felix Pie. Right now I'm platooning Dan Johnson and Casey Kotchman at 1st, with Giambi on the DL, and possibly getting suspended. Thanks..
