The last time I checked, you can have power run elements, with a fullback, and still have spread concepts. Marquez had a drop, it happens. That said, I would prefer it if we used Herndon as an H-Back/FB, he can block, and with his ability to catch the football, he would be a deadly weapon out of the backfield. I'd love to also see more toss plays, to where Walton/Yearby are out in space. Don't run into the teeth of a defense, if they are loading between the tackles.
