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

I might be wrong but I thought they said during the broadcast that Jamies didn’t have the touch or just didn’t like throwing to RB out the backfield
It is and was mentioned by coach as well.
I think that is a fan narrative. Besides the best set for that option route is Kamara in the backfield but in a wide set or closer to QB with motion and then the option route, which is upfield and a cut based on the defender position. It’s not a flat pass or screen.
May be pushed by fans now but CSP has spoken about it too. Winston does not like to throw to the backs, I’d imagine it’s because touch passing isn’t part of his game. (I’m a Jameis fan and am pulling for him)
