I understand that fans see what they want to see, but after watching the sequence back a bunch of times, I noticed a few things:
1) Nick Nurse is a liar. He said he called a timeout during the inbounds and the ref looked at him and ignored him. This isn't true when you watch the tape. He put his hands up as if to call a timeout, but then he stopped himself when the ball was put in play. By the time he firmly did signal timeout, we were already wrestling the ball away from Maxey.
2) Brunson tugs on Maxey's jersey before he receives the ball, that is true. Refs could have called it. They also could have called the push off Maxey did on Hart when he was trying to create space to receive the inbound
