A couple of things are not being factored in this discussion. First, we all know Zeon has been contacted indirectly by other programs. But, now I would think his options will be limited because there is a good chance he won't be able to participate in spring.
Ben was still on a cart for the ULM game, will he be cleared to practice by spring? If Zeon remains, which is more likely than before he was injured, he is the guy. They made that decision clear when he started over Fields. Now, if Ben is cleared to play it makes sense that he returns because of his leadership and experience in FBS football. Otherwise, your QB room will be filled with freshmen and RS Freshmen QB's as backups. That is not exactly a good position to be in considering Zeon could very well be inured again in the type of offense ran by this staff.
