in the end, the coach decides who plays and how much they play.
if the coach fails, he gets fired.
so, unless the coach is nuts or wants to get fired, he is not going to deny playing time to players who - in the coach's opinion - can help the team win.
TT did not play. Ergo, the coach did not think he could help the team win.
Now certainly, the coach could be wrong. but if TT ever sniffs the court on another major conference D1 program, I will be extremely surprised. TT was billed as a big man who could shoot from the perimeter. this season, he made 3 of 25 3-pt FG attempts. that's 12%.
