Why does our 5'6" receiver not do more comeback routes?

Well, Darren Sproles was a receiver coming out of the backfield. A lot of the concept created for Sproles was used for Kamara.

Darren Sproles as a LOS WR wasn't that productive. Harris is exclusive used at the Los scrimmage.

Even though, Harris is the same height. He is more comparable to Steve Smith and Tyreek Hill. Who also got 3-4 more inches on him.

DS was used in a non-typical RB way more than you probably remember. HIm and PT lined up in the backfield together, creating mis-matches, people don't know who the heck is doing what. A lot of our best offenses have been based on mismatches. Kamara and Harris line up in the backfield together, who are you going to sell out to stop?
