First, I think we keep 4 backs. Don't know if Jones is better than Kelly Or any other back in camp, but if any of the big 3 get dinged we need a RB. Second, maybe that third or fourth back becomes a KR/PR. Usually some of your better ST players at RBs. Brown was a terrific KR and probably won't be used that way right now since he might even start and I remember reading that Jones might be strong on STs. This, I thought that there was a 55 player roster. Why is everyone predicting who makes the final 53? Carrying an extra back or TE makes sense with a bigger roster.
