You could argue the running back position, along with the linebacker spot, are the only two spots where Hugh Freeze and his staff have yet to recruit and cultivate a real star. The running game has yet to feature one guy that could make big plays, while also making the small plays. The small plays being the short-yardage, physical runs.
However, the running game has been back on forth during the last four seasons, sometimes providing a serviceable compliment to the passing game with splash plays here and there. However, there have also been those times where the running game has stalled brought about frustrations also.
