In one league, im deciding between percy harvin and mario manningham.....im leaning toward harvin, bc he is really the only decent wr on Minn, but manningham will have the better matchup vs wash...thoughts?

in another league, my third wr options are garcon, crabtree, or knox........i wanna stay away from garcon bc theres no peyton, what do you guys think about crabtrees value against seattle?
