My only gripe with Kyrie is he became a bit of a ball hog at a point when the Celtics started losing, after that great start. That doesn't work with the Celtics. They must have ball distribution and even scoring to be successful. With Rozier, they are back to doing exactly that. So Rozier must be doing something right. Kyrie is watching and absorbing all this. Maybe he's getting the message.
Ainge has some serious decisions to make in the off season. Perhaps whatever happens in the playoffs will be a factor. So far, so good. And the cap situation is always a determining factor.
