Trade for AB? - What is it worth?

Footclan,

Sitting in second place with a 4-1 record in a 12-man full PPR league. I like my team a lot, but always looking to improve. The manager with AB is willing to trade him. Is he worth going after and if so what should I give up for him?

QB - Rodgers / Lance
RB - Chubb, Edmonds, J. Conner, Gordon, L. Murray
WR - Hill, Samuel, Pittman, Patrick, Cobb
TE - Andrews
K - Tucker
IR - Wilson JR.

Thank you!
