I have Antonio Brown and have been offered Doug Martin and Willie Snead. Snead I have no use for. PPR league.
I don't think so. Unless you have a strong corps of WR's and really need a RB, then I'd probably just hold on to Brown. I know it's concerning with Big Ben seemingly hurt/not-hurt with no rhyme or reason, but that team likes to pass, and Brown is one of (if not the) best in the game.
I have A. Robinson, L. Fitzgerald and R. Cobb. I have L. McCoy, J. Stewart, S. Draughn, A. Andrews and K. Williams.
