The easiest way to measure team chemistry is to see how many players come to a teammate's aid during a fight. For good teams like the Wizards, the answer is everyone. For mediocre teams like — I don't know, the Pelicans? — you have a couple stragglers, but it's still most of the bunch.
For the Knicks, now 5-26 after losing 102-91 to Washington? Nobody. Not a single soul dared approach the scrum to help Quincy Acy after he and John Wall got into it. Great chemistry, Knicks!
