Fantasy HUGE trade offer?

I'd rather have MJD-McNabb over Brees-Portis. MJD is one of the top 2 players to have, seems to put up multi-TD games more than anyone else in the league. I'm sure that's the higher-scoring duo in this trade. Obviously Brees is the best QB to have but McNabb is no slouch, and maybe that team has another QB who is good as well. The separation between top and mid-range QB's isn't the same as among RB's. Can't say I'm interested in the third players, but if the team getting MJD also has Thomas then it's even more of a no-brainer.
