should I trade away APeterson for RGrant + Gates + Flacco?

[fasttwitch]

I have a good team but some weakness at QB (I have McNabb and Garrard).
I'm in a standard ESPN 10-team league. NOT PPR.

My buddy has devised a 3-way trade where he needs Adrian Peterson, and I need an upgrade at QB. I am worried about McNabb.

he's offering me:
Ryan Grant
Antonio Gates
Joe Flacco.

i give up:
Adrian Peterson

Should I do it?

My lineup now:

QB: McNabb, Garrard
RB: APeterson, Ahmad Bradshaw, Brandon Jacobs, Leon Washington, Jonathan Stewart
WR: reggie Wayne, Dwayne Bowe, Steve Smith (NY Giants), Steve Breaston, Jericho Cotchery
TE: Brent Celek and Visanthe Shiancoe

He needs AP? Obviously everyone "needs" AP. Absolutely do not do this trade. Look at what you are getting. Yeah, you might be getting a slight upgrade at QB over McNabb but you are giving up the best player in the NFL. Don't mess up your team on this trade!!

Plus Grant is on the verge of getting demoted. GB coaching staff is not pleased with Ryan Grant this year.
