After rookie Tre Mason appeared to take a leading role Week 7 against Seattle, rushing for 85 yards and a touchdown on 18 carries, the Rams went running back by committee again Week 8 at Kansas City. Mason led the team in carries, but he had only seven. Meanwhile, Zac Stacy got five, and Benny Cunningham got four.
Stacy was once again the weak link, gaining just 17 yards. Though he's been the Rams' leading ball carrier this season, his longest run is only 16 yards. In this game alone, Mason had a run of 14 yards, and Cunningham had a run of 18 yards.
Coach Jeff Fisher said prior to Week 8 that Stacy could get 25 carries against the Chiefs, but clearly, he wasn't effective enough to justify so many. Frankly, he hasn't been effective enough to justify any at this stage of the game, but the Rams need more convincing. Because Mason was again their most effective rusher in Week 8, it's probably just a matter of time.
Of the three, Mason is the one to own right now even if you can't start him just yet. Cunningham has some appeal in deeper PPR leagues. Stacy is probably just a waste of a roster spot.
