I think we have seen the offense become more and more of a hybrid over the last few years going from the traditional single back (or i-form) with some spread formations to the pistol to the wildcat to adding the read option with Blake (and even Coker and Bateman last year). I dont know if Kiffin or Saban would be very comfortable just doing a spread style package with Jalen in the game unless they just want to utilize him, kind of like the Wildcat, with read option, but if Bateman is your guy why would you need Jalen to do the read option? Bateman is supposedly the fastest guy on the team (that may be pre-Jalen but I'm not sure). If the coaches think Jalen is the guy he needs to be the guy. Otherwise he needs to shirt.
