yeah its all a joke the "talent" they wind up drafting, go look at the draft 3 years and 4 years ago, most of those guys stink. They have no problem picking up a small school kid that is black. Teams that are majority White, teams will pick up the one black guy on the team. They do it for FBS too, like Boise St back in the day.
They will use competition against Zenner, but Melvin Gordon who everyone is hyped up about, only got stopped one game so far, it was against Western Illinois, an FCS team, not even a powerhouse like the teams SDSU has to face (NDSU being the main one), they held him to 38 yards on 17 carries. 2.2 ypc.
Terrance West played tailback at little Towson and is more stereotypically fullback-sized at 5'11" and 230 pounds yet was drafted in the 3rd round by the Browns strictly as a running back. He's had a couple chances so far to be Cleveland's featured back but is ordinary, nothing like the highlight reel Zenner has been and might be in the NFL if given the same opportunites.
