I was always on team Belo, but as the year went on did begin to question if he would ever fully develop into someone you really want as your 1A playmaker and offensive decision-maker, but always gave the benefit of the doubt given the craziness of his year.
The point I turned was the NCAA video interview preview of the Houston game, where he seemed checked out to me (certainly not dialed in like you would hope) and imo did not represent himself or the team and university well as he ate his chicken sandwich and fries (during a 10 minute national media interview) and gave glib, rote answers to the media (we're going to do what we're going to do, etc.). In hindsight, recognize that he already knew he was gone at that point, but still a disappointing final performance. Talented player, but fresh start (and new Illini PG) seems like a good idea for all.
