Jake - do you keep Hasselback in a Yardage-only league? I would probably replace him with O'Sullivan (already have A Rodgers).
I'd keep him over O'Sullivan at this point. He'll do better once his WRs finally get healthy in a few weeks. O'Sullivan made some bad throws last time out and you have to question how long he keeps ahold of the job.
Alex Smith has a injured shoulder and may be out awhile. He played under Martz in Detroit. Of course I'm sitting on Engram too.
