I think w/ the options you have available, you have to roll w/...
Megatron - he is still your best WR even if he hasn't looked like it, he really needs Stafford back (and hope for a garbage score)
Crabtree - Eventually he has to breakout doesn't he? ATL's secondary is garbage & SF should be playing catchup most of the day.
Edwards - Bills suck, only worry is the Jets just run it down their throats.
Thomas & Wallace are both tempting & both could perform better than your other options, but Wallace gets the Ravens (and Batch really isn't very good) & I have a hard time trusting rookie WR's when I have other options.
