Kyrie has nothing to address. He stated to the public before the season he is staying in Boston. Then he shot down the Jimmy Butler rumors and said he wants his number retired in the rafters of the Garden.
Guess what? That was for the public. If you think Ainge and his team mates do not know what Kyrie's intentions are and so he needs to address this to them, you are being naive and a bit foolish. Kyrie is in constant contact with management, coaches and team mates. When stuff like this comes out I am sure they talk about it, maybe even joke about it a bit.
There is literally no reason to address this publicly except to make insecure fans that believe everything they read on the internet and social media feel better about what they read or heard.
