I get what you're saying, but it's actually the opposite. Chip sets his runs up via vision, that Henderson has lacked. His stutter move in backfield against Indiana was border-line elite. His lane was cut off, he paused in backfield to read LB, then found the edge with elite explosion when the run lanes were clogged.
People forget that Trey was a CB most of his upbringing in football and only became a RB in his sophmore year of HS. He doesn't look natural at RB, and there's a reason why....he isn't natural at RB. His attributes for the position are freakish, but he just isn't natural at it. Will he make an explosive play periodically? Yes. Does he keep defenses honest in screen game? I think so....
Is he better than Chip or Miyan? Nope.
