Every mock I have read including the Steelers insider guys only have 2 RB's listed. Najee Harris and if he is not there, Travis Etinenne from Clemson. They want a guy who can on any given play, take it to the house. Both guys I listed are very talented and the top 2 rated this year. Some people question Harris as a pass catcher, but like he said "I didn't need to be a receiver, we had 3 NFL draft picks for that." Etinenne is a very good possibility (I think Harris will be off the board before then), and is is a very dynamic and dangerous RB, maybe not 20 carries per game, but very skilled both running and receiving, a true game breaker.
