I've blamed the players as well at times, calling Jaylen, Jayson and Joe , the dumb, dumber and dumbest trio.
Funny thing is that Mazzulla had them playing offense with a lot of off-the-ball movement and screening and quick ball movement the first half of his first season after being named interim. They were setting all sorts of offensive records (with no Porzingis or Holiday on the team) and I have no idea why the team stopped playing that way and why Joe let them. A coach is fully capable of dictating a team's offensive strategy, even in the NBA. If a player insists on going iso constantly, you sub him out. But Joe has stated that he wants a 3-point heavy offense including the shots off of iso-dribbles. That style of offense almost always gets the team in trouble and they lose big leads or lose games with it.
Ime's offense was just as bad, maybe worse and it cost us the title in 2022. I'd say Brad's offense had more creativity and movement, but by the time the team became talented enough to win big, they had tuned him out. I hated his small-ball, 3-point offense as well. What is it we have won the past 8 years with this style of play ? Joe is the coach now, so it is his job to correct it.
