How should I start and who to bench?

I am in a standard leage not ppr. We start 1QB, 2WR, 2RB, 1TE, 1K, and 1 Team D. These are players on my squad.

Matt, Ryan againts 49ners
Jay, Cutler bye

Calvin, Johnson againts Pitts
Mike Sims, Walker againts Seahawks
Marques, Colston bye
Roy, Willams againts KC

Diaglo, Willams againts Redskins
Marion, Barber againts KC ( Worried about quad injury. He did not play in second half last week.)
Knoshown, Marino againts NewEngland ( Buckalter is hurt and he is supposed to get first start)
Keving, Smith againts Pitts

Thanks for anyhelp making up my mind.
