I have read news that the Celtics players were caught off guard about Ime Udoka's case. Majority of them found the news in twitter like Jayson Tatum and so they are confused.
And then they are talking about how excited they are to come back this new season to do it all over again and duplicate what they have accomplished - go to the finals. But it seems that the players are affected by it and they are taking about the 'process', as they will be coach by Joe Mazzulla.
It's easier said than done because these players already established some high chemistry with their coach and they trusted him a lot in terms of coaching them and now that he is not there anymore, it will be a huge change in how they play because it is not the same anymore, this new coach has a different way of coaching and a few games this upcoming season will tell us if he really fits with the current Boston Celtics rosters. It's not that easy to just simply change coach, just look at the other team, they want their coach to be removed or to be changed this upcoming season.
