Fantasy football trade?

My current team:

QB- Rodgers

WR- D. Thomas

WR- Cobb

WR- J. Brown

RB- Forte

RB- McFadden

TE- Gates

WRT- Ch. Johnson

BN- Rivers

BN- Carr

BN- Witten

BN- Lafell

K- Hauschka

DEF- Cincinnati

The trade:

I give up Rodgers, Cobb, McFadden and Gates

I get Brandon Marshall, Dez Bryant, and Drew Brees

My roster would then look something like:

QB- Rivers

WR- D. Thomas

WR- Bryant

WR- B. Marshall

RB- Forte

RB- Ch. Johnson

TE- Witten

WRT- J. Brown

BN- Lafell

BN- Brees

BN- M. Floyd (off waivers)

BN- Carr

K- Hauschka

DEF- Cincinnati

I would then try to trade Brees away for a running back. I'm trying to upgrade my receivers getting rid of the inconsistent Cobb and replacing Rodgers with Carr and rivers. The Gates was an extra incentive for him since I have Witten. What do you think?
