Question about trade - involves Mendenhall and Austin

[heavysoul]

In my non-keeper, standard-settings ESPN league, I have been proposed the following trade:

I trade Rashard Mendenhall, Donald Driver, and Brett Favre
I get Miles Austin, Reggie Bush, and Jabar Gaffney.

Pull the trigger? Counter-propose for LeSean McCoy instead of Rashard? Here's the rest of my roster:

Starters:
QB Drew Brees
RB Arian Foster
RB LeSean McCoy
WR Mike Williams
WR Brandon Tate
TE Dallas Clark
OP Tony Romo
DP Kevin Burnett
D Jets
K David Akers
P Matt Turk
HC Colts Coach

Bench:
WR Dez Bryant
DE Jared Allen
RB Mike Tolbert
WR Lance Moore
TE Heath Miller
