Think you may have your Alex(es) confused. Alex Davis is a guy on board with the coaches but is horribly unproductive. 5 tackles this year. Five. Remember, he started over half the games and played tons of minutes. Quay Alexander has never moved the needle. All sorts of questions regarding his desire to make it at the D1 level.
Alex Davis is a guy with the athletic ability to be a productive OLB, but not the aggressive attitude and demeanor. Of course it’s too late now, but he’d have been better off as a tight end. Even with that, he would have had to learn to block. He was a project from the start, given his limited experience as a football player prior to college.
