NBA.com just released the Advanced Stats for the game and they're pretty telling.

The Knicks won the shot margin - they took 92 shots vs our 79, and they made 50 of them vs our 38. They made nearly double the amount of 2 point shots that we did (Bridges and Brunson killed us from the midrange and KAT killed us with those floaters in the paint. The Knicks scored 64 points in the paint - twice as much as we did, and 22 of them were in the last quarter when we were running our two-big lineup of Al and KP. They shot nearly 70% in the 4th quarter - only made 2/4 3s but didn't need to with how much they scored in the paint. Again, a failure in execution by the players, this time on the defensive end, which is unfortunate since we actually shot ok this time - not as good as G3 but should have been good enough to win the game if they showed more connectivity on defense. And I think Joe has some accountability, I know Jaylen was having a bad game but 5 mins in the 4th quarter?
With JT most likely out, Joe will have to make some adjustments. He's got no JT, no Sam and KP as a passenger. Someone from the Stay Ready group might have to step up, unless he wants to go with a seven man rotation (given it's win or go home he may decide to keep playing time to his circle of trust). I'm guessing he does the latter and everyone plays more minutes, and he starts KP with Al at the 4 to replace JT. We'll see how it all works out.
