Before the season, I had Martinez as #1, then Fletcher, Lyle, CJ and AJ in that order, but given how well the backups have performed (albeit inferior competition) I will wait until after mid season to revisit this question. I just hope the coaches play the best, not play politics or favoritism. I think they will.
No insult to Martinez or Fletcher, but a compliment to the other RBs in the room who continue to develop and improve. Let your performance on the field determine your snaps
