Mason said Thursday that Rams coaches told him he will compete for the starting job in the team's backfield this season, according to Ryan Van Bibber of SBNation.com. This is probably news to Zac Stacy, who played like a rising star during his rookie season in St. Louis.
In all likelihood, Mason is parroting a variation of the competition mantra that's gotten John Idzik into some trouble in New York lately. Rams coach Jeff Fisher said in March he believed Stacy will become that "70-percent of the carries guy."
If Stacy is allowed that type of workload in 2014, Mason is more likely ticketed for a change-of-pace role to start his NFL career. Mason should get his opportunities, but Stacy should carry the show.
