I don't really care that much about Kyrie's peace of mind or whatever, other than how it impacts how well he will play in the finals. Maybe he truly has found a good place, realizes his mistakes of the past, maybe this is just a phase, a temporary thing, and he will flake out again at some point.
All I care about right now is how he is going to play. It appears that he has pulled himself together enough that it will likely last through the finals. Booo to that. Maybe some of the Celtics who know him, know something that will trigger him, and they can whisper that in his ear and set him off to being the old Kyrie.
