It's only a 10 team league so I will have players to replace Fred Jackson with but here goes:
I would give - A. Bradshaw, A. Gates, J. Nelson, CJ Spiller I would get - M. Lynch, A. Hernandez, Cal. Johnson, F. Jackson
I have Ray Rice as my other back and would be able to play Calvin, AJ Green and Julio Jones as my two WR's and flex while waiting for Fred Jackson to come back. Right now I have Nelson, Spiller, Bradshaw filling two spots. The depth would help me down the road but right now makes for tough decisions.
If he asked for Green over Nelson it would work. For Jones over Nelson . . . . that would be tough to accept. Depends on how bad you want Megatron. And Jones is on his way to approaching Megatron's status in both the NFL and fantasy.
You take Megatron and Jones out of the equation and the trade becomes Bradshaw/Spiller/Gates for Lynch/Hernandez (Fred is hurt/broke and a throw in so he really doesn't count here). The trade then sways moreso in his favor on paper.
