I don't think there's much to be worried about. Giving AP just 4 carries in the first half was detrimental to any chance they had of establishing the run with such a terrible o-line. I thought he looked pretty good as a runner considering he hasn't played in a year or so, plenty of YAC. Promising signs out of the backfield in the passing game though. Improve the o-line and play calling and he should be fine.
