Brunson is essentially early HOU James Harden, except he plays in this era, so he already has the elite shooting down, and because of his size he actually developed the midrange game.
Like James, Jalen has developed his hesitation moveset to an elite level, right now only Luka and Donovan are on his level in that regard. He gets the defender on his hip, and depending on how he feels their weight will go into his actions. They put a body into him and he draws the foul (this is what's making all of us mad, just like early Harden
), bounces off for the middy, or takes it to the hole with the defender a step behind. They try to cut his angle or drop, and he's pulling up or passing out where he will reset, and do it all over again
For all the hate Thibs gets, and being known as only a defensive coach, he has this Knicks team running a ton of off ball action, and a lot of the time Jalen is able to break his man down as his team mates are breaking the defense of the opposing team, and you're seeing him take advantage of this action a ton. Defense is always either late, sloppy, or conceding the shot to his open team mates. Dante has been feasting off of these actions all year, and Hart and Isaiah are getting offensive boards like crazy because of it.
I'm honestly surprised more people don't give him the Harden comp really, their games are eerily similar. Brunson just uses the midrange shot, but all the moves are the same
