Which 1 of the 2 RBs should i start this week? chris johnson or adrian peterson?

See as much as i like chris johnson and agree with both of the previos two answers, i say start peterson. He is going up against arizona and he should be able to torch them and prove to everyone he is an elite rb. Johnson is a HUGE player, but hes going up against indy which will no doubt be focusin on stoping johnson. Indy is a good defense and i believe will contain johnson. Good luck
