Leonard Fournette usage in the red zone

I do not understand it. Leftwich calling his number down there yesterday & games before is just head scratching. He is the tip toe burglar of the NFL. He runs soft despite his size. I know coaches see the film. RoJo needs those reps down there. And despite Fournette being good in pass pro supposedly, he got Brady killed on that 3rd and 15 bomb to Godwin. Vaughn honestly couldnt be that much worse moving forward.
