I'm not familiar with the details, but I doubt our coach felt the sudden urge to torpedo the season just because D'lo looked at him wrong. The fact is Lavin is the HC and he will be here before and after the players. This is his program and if in his opinion he felt like one of his players was disrespecting him, his fellow coaches, or players on the team, then he is well within his right to do so.
I hope beyond hope that D'lo views this as a wake up call. He's a very talented player and I feel like he would get even better if he came back next season. Whether that's in the cards, I don't know but I hope this isn't the end of him at St. John's
