Would you trade McNabb for T. or J. Jones...?

[SammyKid11]

8-team league...

My QB's - Carson Palmer, Donovan McNabb
RB's - Shaun Alexander, Westbrook, Mike Anderson, Fred Taylor

My thinking is...obviously, McNabb's stock is hurt by no T.O. -- plus I have Palmer, who's been the most consistent fantasy QB in the league. I have Alexander who's an every-week starter...but after that (Westbrook, Anderson, Taylor) I have three guys that are every-week MAYBES.

My possible trade partner needs serious help at QB, but he's got Edge, LJ, Thomas Jones, and Julius Jones...he's looking to unload one of the Joneses in exchange for a QB.

First, would you trade McNabb under these circumstances for EITHER of the Joneses? If so, which one? They're both coming off injuries, but were both effective earlier in the season. Julius is back sooner, but Thomas was more effective earlier.
