In regards to the RB's, Stewart is your best bet. I don't think I can trust any player's from the Browns or the Raiders regardless of who they are playing.
As for WR's I would go with, Harvin, Walter, and Meachem. I was initially going to say Moss instead of Meachem but based on defensive match ups I like Meachem. I have a feeling that Colston will be double teamed alot which could offer more opportunities for Meachem.
i would play Walter. he should have a good game against Tennessee's terrible pass defense. and i would play Harvin against Seattle instead of S. Moss. it looks like Washington is going to start playing Thomas and Kelly more at WR during the final games now that they are out of any contention.
and if Lance Moore is still out i like Meachem against the TB defense. he is fast, gets targeted on long down field routes and has scored two weeks in a row.
but i think the real choice you have is then between Garcon and Harvin. Harvin has been pretty quiet of late and Manning is on fire. i would go with Harvin but i think it is a tough call.
