Moreno was inactive but was still obviously the #2 fulltime back. To say he was 4th string is retarded after he just started and got all but 4 carries after Willis goes to IR. I would guess Hester will fill that role now of being inactive unless Moreno gets injured.
Hillman is our situational back and Ball is a STer which is the reason they were active. They were not ahead of Moreno on the real depth chart. I would think any idiot could deduce that.
