I remember that Terry Francona said that managers get too much credit when teams win and too much blame when they lose. I think that applies to basketball also but maybe not as much as baseball.
I hate to say it, but I am not impressed so far with the coaching. It is just a kind of observed thing but when I watch a team, sometimes you get the impression that it is a well coached team and other times not so much. The Celtics have not looked like a well coached team this season. Referencing the quote by Francona, it may not be all Ime's fault but he is the coach.
I feel the defense has improved lately. The team seems more comfortable with the scheme. They are not trying to switch everything but if it is a guard picking for a guard, they switch, a big and a guard, they try more often to fight through it. That side of the ball looks good and probably will continue to improve.
On offense, I don't see a solid scheme. Again, I see some improvement but too often, they just don't look like they have a plan. They run a pick and roll or two or three, then someone is doubled, and it just kind of breaks down. The plan or scheme only seems to extend to the ball handler and the picker. The other 3 players don't seem to do anything but wait. Everyone should have a read and a reaction. The offense is just not that evolved yet. That is coaching first and execution second. It does not appear to me that the plan is there so there is no execution.
