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

It just feels like Harris can blow up for a big play on every down if we use his strength.

Yet, it feels like we gave him routes meant for Devery Henderson and not something that meant for Harris.

His route calls doesn't take in account for inside leverage. When you 6ft tall... It doesn't matter. Harris isn't and it's just weird.

When send him to the sideline like that.. He gets pinned and he won't be able to make a play unless there is a comeback cut to beat the brakes off a CB to shift him open. It's wack.
You would think that less than 10 years after having Darren Sproles on our team that CSP would know how to use someone with Harris' size and speed properly in the passing game.
