Imo Trey is not good enough to be a rotational player on a big 12 team. It doesn’t matter how rotten a coach is, if you refuse to go into a game as a player then you are being a brat in that situation. There is no alternative explanation unless you physically can’t play.
Even if the coach lied or mistreated you…if you don’t enter the game when your number is called then you probably shouldn’t be on the team at all.
