I am not that surprised by the result of this game. NYK is good. Brunson in the P&R is lethal. They are going to be a tough out in the playoffs.
But this game was a Thursday night in New York where BOS was without their best player (at least this season). And the other best player didn't have a great game. Some players played way above their pay grade (Hart, Scheierman), others played below. NYK was better last night and they won the game. I don't think BOS played great, certainly could have been better, but they were right there with a chance to win without Brown and in spite of it being something less than their best overall.
I will say that I think they need to do some different things to defend the Brunson P&R. They may be saving some things for the playoffs, I don't know. I think you have to double Brunson off the pick but then there should be rotation, not just the big trying to sag back to get back to Towns.
