My WRs are Mike Wallace, Sydney Rice and Mike Williams (TB) and planning to sit Williams this week. Williams scores single digit every other week so I really don't feel like starting him over a RB. But then there's a good chance that all these 3rd RBs will score single digit also.
I wouldn't do that too.
It's funny how things have changed since the draft... I picked up Peyton Hillis when he was available and now he's the best RB in my team, beating my 1st pick Adrian Peterson. And the guy who picked up Vick has the best chance to win all the way.
