RB2 help- mendenhall, murray or sproles

[ascrambler]

was burned by sitting sjax and mendenhall last week and starting murray and sproles instead. this week i'm for sure starting sjax @ ari but who should my RB2 be?

murray vs sea
sproles vs TB
mendenhall vs balt

sea has good run D and mendenhall doesnt make much sense against baltimore's D so go with sproles? just dont know what to do...

always play your superstars mendenhall all day
