Which 2 RBS do I start this week and why?

Brandon Jacobs is a no brainer and You can flip a coin on the other 3. Jacobs is still the #1 back and Arizona can be beat with the run, yeah he will split carries with Bradshaw but still expect him to have nearly 100 yds and a td. The other 3 are pretty much all even. Mendenhall will split with Parker and Moore, but still get a good number of carries. Maroney had a big game last week but still isnt proven to be a week after week guy. If NE gets up again they could go back to him late in the game and see what hes got but i still see Tom Brady playing most of this game. Thomas is always solid but if it becomes a shootout will get a lack of carries, if Miami plays the p tough, then he is going to have a big day.
