Steelers GM Kevin Colbert believes rookie RB Najee Harris is ready for a 3-down role right out of the gate. "Him coming in as a senior out of college, he has more experience than some of the other underclassmen, so I think that will help him transition," Colbert said. "He's coming out a traditional NFL-type offense that should help him transition." Harris has the experience and talent to capture a huge role this season. And there isn't a legitimate threat for work behind him on the depth chart. We only have 4 RBs projected for more opportunities (carries + targets) than Harris.
