Kawhi situation was definitely worse, but the Jazz need to be careful that this doesn't go down the same path. Don already does not trust the training staff, that is what he has in common with Kawhi. You don't want this to linger and for him to not trust the whole organization like Kawhi.
I just can't imagine a situation where the training staff is too shy to put Mitchell on the injury report but confident enough to rule him out a couple hours before game time. It is literally against league rules. It does feel like a power grab situation from the training staff and even if it wasn't...you have to think Don and the players feel the same way.
I also think there was a joint decision here where the training staff wanted to show their authority, but maybe the FO thought they could probably win without Don (we should have) and didn't mind being extra cautious. That's why the FO allowed it. It might have been fine if the team won or the players weren't blindsided...but you can't blindside your whole team and then lose.
Don is not the only one pissed right now. Somebody is losing their job over this. Pure ineptitude to blindside your entire team right before a playoff game.
