retires from football due to head injuries (as some suggest may happen), and if he doesn’t believe that Koy can play D-1 ball, then he’s looking at another train wreck season in 2018 if he can’t find an another answer at qb.
I may be way off with this guess. I think it’s a bit premature to write off our 1st-3rd string qbs, but from the sound of his media sessions, he may have already done that.
