We have heard all about Leonard Fournette, Christian McCaffery, and Dalvin Cook as rookies who can take the number one running back position for their teams. There is one rookie running back that nobody is talking about though. That running back is the fourth round selection for the Indianapolis Colts Marlon Mack. Mack definitely can take the number one spot in Indianapolis. He played at USF for three seasons, and rushed for over 1,000 yards every season.
Mack has taken the league by storm with the limited action he has gotten in the preseason. With Frank Gore getting up there in age Mack could be in for some serious touches in 2017.
