Everyone is dying to get a Sean Payton running back, and Dobbins could very well see the bulk of the early-down carries in Denver. RJ Harvey is not the stud prospect that everyone is making him out to be. Could Harvey ultimately win the job? Sure. However, he's far from locked in ahead of Dobbins, who is coming off a solid season in Los Angeles in a season in which he was coming off of a serious injury. Last season, Dobbins averaged 4.6 yards per carry and totaled 905 yards in 13 games while scoring nine TDs. He added 32 receptions for 153 yards. The snap share between Dobbins and Harvey will be much closer than fantasy owners are hoping for.
