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.
Well, they have no choice but to accept the reality, no more Udoka this season and probably the succeeding seasons as well, but they have a job to do, it's an unfinish job, they reach the NBA finals, it's time for them to win this time.
There's plenty of time to make the adjustment, the current coach is the assistant, so I'm pretty sure he is very much aware of the system and he just need to implement it, we were impressed by Udoka's performance last season, but he made a big mistake, so he has to face the consequences.
