Ainge ruined the team's chemistry this season in his pursuit of Anthony Davis. Additionally, not working with Stevens to establish a clear hierarchy on this team had led to chemistry issues.
Tell me that in the back ofSmart, Brown, and Tatum's head they are not thinking I might not or probably will not be here next year (I'll be in NO) so I do not care so much what happens. (ok maybe Smart not so much)
Rozier and Morris (FA's) might be thinking the same thing. That is practically a 1/3 of the team that is partially mentally checked out.
Kyrie dealing with all the media non-sense as well is thinking who will or will not be here next year. And if he is thinking about leaving, then he is mentally checked out as well.
Ainge did not forcefully address this issue, he should have CLEARLY stated we will deal with the offseason in the offseason and worry about Anthony Davis then. Additionally, he should have warned NOP that if trade talks leak, the price willing to be paid goes down. And let face facts, if somehow, this team wins the championship, are we going to blow it up for Anthony Davis? If Tatum averages 22/8 in the Finals that the Celtics won, are we trading him?
By indicating that this squad is not good enough, and that A Davis is what is needed, the chemistry was ruined - gone! It is everyone for themselves! And it clearly shows.
Stevens is at fault as well by not setting the hierarchy and clearly establishing the #1, #2 and #3 options on this team. As stated in other posts, Stevens' anyone can shoot and should shoot theory of offense works best with a squad that does not have premier players/scorers. When you have a Kyrie level talent, he has to be your number 1 offensive option- every night! As a coach, you tailor your offense around that player. (As an aside, rarely does a team whose primary scorer is also the PG win championships (GSW is an outlier because you can also argue that KD is also a #1) I think having the ball in one players hand too much causes the other players to zone out, especially if they are top level players as well.)
Stevens has (as far as we know) not told lesser players to get in line and stick with their roles, even at a sacrifice to their stats. A team needs scorers, defensive specialists, 3&D players, etc. These roles should have been assigned and enforced. If a player is not happy with his role, he should be moved. Take Rozier for example, if he is not happy coming off the bench as the back up PG, then move him for a pick or 2 or a player that will be content being Kyrie's backup.
