Short Corner

That's a 4-year-old tweet. Evan actually pegged Morris as the back to own in SF .Giving the benefit of the doubt to Silva that his point is the read option and RG3 helped Morris rushing efficiency because of the dual threat. Which isn't the point you are making, that Morris has declined since his first two years when he was with Skeletor Jr. who he is now reunited with.
Morris decline in YPC is significant but just as likely a product of change in coaches to Gruden who was looking for a RB who could catch the ball more effectively than Morris can as RG3 being the QB.
Looking at ypc for the first sample of 33 games makes more sense than it does in the 2nd sample of 12 games. The two samples are not really congruent.
