Hine would get more time at RB but he seems lost sometimes with the footwork, taking handoffs, etc. He seems to hesitate at times for a split second after the snap, which can cause all sorts of problems, but there's no doubt he's a physical specimen that is an open field monster.
I played safety and receiver/tight end in high school and I was hard to tackle so the coaches wanted to see me try out running back in camp my senior year and I completely failed at the footwork and taking handoffs during the experiment; I just wasn't comfortable and it showed, even though I was excited to get the ball and bulldoze some peeps; they moved me back to my positions of comfort, and instead threw to me out the slot instead of trying to teach me a brand new position. In the slot....Hine could certainly make some noise in Falslevs position but JD has been quite reliable. Hine out of the slot to get him the ball in open space would be dangerous. Glad he's got plenty of time left in a BYU jersey! From all things I've heard Hine is very intelligent and sometimes rb's can overthink the position, when it's really "set up and go" (I'm not saying it doesn't have a cerebral facet but rather you don't want your running backs thinking as much as they instinctively go.. and that means the footwork has to be so natural that you're not thinking), I have no doubt he'll figure it out in time.
