It could of very easily been a situation where it happened, Dabo addressed it privately with said coach/player, and that was the end of it. Tuttle could've heard about it or heard it himself and was mad it wasn't addressed publicly in front of the team.
I think this is the most plausible scenario.
But if your situation is true, and Dabo didn’t fire the coach then what? (I don’t recall anyone being fired but maybe I’m wrong). You can’t make a mistake like that and not get fired. Firing them now does nothing either.
I’ll say it...if your situation is true and all Dabo did was have a talk with them, then they all need to go. A private talk isn’t enough.
