I believe this was a trap game and said so before when I learned Melo was out. Without Melo the talent of the two teams isn't that far in favor of the Knicks, ad even if the Knicks are more talented than them without Melo, they were coming of a game the previous night and it was a game they went all out. There just wasn't as much emotion in it. They played well in spurts, but without Melo you see a team that has a ton of role players trying to create shots and work harder on offense. That weakens the effort left for defense. I know if Melo is out for a significant time - like 7-8 games, the team could figure it out and be competitive.
Certainly think if Porzingis isn't tired and playing like he has been previous 5 games in terms of shooting the ball, they can win. Porzingis just didn't have his shot tonight. Everything seemed a bit off. Without Melo, really needed Porzingis to play like a star, which he was willing to do (took 17 shots and was aggressive in calling for the ball and taking shots) but unable to convert them.
Real stinger - hate losing to a team we're better than. This is part of the regular season grind though. At Memphis will be another tough game.
