I wasn't looking for a trade, but this was proposed. My league starts 1RB, 2WR and 2WR/RB flexes.
Starting RBs - Javid Best, Ahmad Bradshaw
Bench - R. Williams, Buckhalter, F.Taylor, F. Jackson, K. Huggins
Starting WRs - Austin, M. Wallace, M. Colston
Bench - Mike Thomas, Jacoby Jones
Basically, I would be able to sub L. McCoy straight up for Colston. I am not super eager for the deal, but Colston worries me. He is on a team with so many weapons. But this trade would hurt my WR depth on my bench. I am deeper at RB on the bench, as you can see.
What worries me the most is that if I trade Colston, although I still have 2 good starting WRs, I have nothing really left if either of them goes down. If I lose a starting RB now, I have plenty on the bench to fill in. But I am always of the mind that a good RB is just going to be more consistent than a good WR.
