If Gurley was out for 3 weeks would you rather MB or CJ?

I think I might like CJ as the #2 back with Kelly as the #3 - that way you have one experienced vet and one young, talented, back. Then draft or UDFA a guy or 2 to compete with Austin Davis. As opposed to only Malcolm Brown and Kelly behind Gurley. Has Brown started an entire game? Maybe, can't recall.
