If you keep graham what RB could you get and then if you keep Mathews what TE could you get? Look at the point differential.
I would keep Graham because I don't think Mathews will put up the points others here think he will. Graham is also the safer pick since he is less likely to get hurt and you can be more certain of the numbers he will produce.
QB: BREES, Cutler
RB: TURNER, MCGAHEE, R. JENNINGS, Leshoure, D. Williams, Hillman, Hunter, Dwyer
WR: CRUZ, GARCON, Amendola, Edwards, D. Baldwin
