The coaches are on record saying that Adrian is the starter and the possibility of a change is "not a story". I hope that Logan is ready to play next season, but the coaches seem to think Adrian is better even with a broken jaw, ankle injuries, and whatever else.
Simply putting the teams struggles on Adrian is an easy way out. The reality is the team struggles tremendously in so many areas (pass blocking, run blocking, play calling, special teams) that a QB change isn't going to fix all of those issues.
