People just discount Brashard because he was misused instead of featured. The other guys are not like him because he has size and quickness for his body type. He is more of a Debo Samuel type. A WR with a RB build.
He could have thrived in a 2 RB system where he'd be a mismatch for LBs. If they put a corner on him, you motion the other RB and run the ball with a light box. If they put a LB on him, he motions as the slot and take the LB to the wood shed.
The NFL is all about mismatches. I watch what NFL teams do with guys of similar size and traits at his position. We didn't even scratch the surface if how he could be used.
