I went frame-by-frame on Risacher's scary fall and caught something the Hawks announcers spotted - Gillespie's late push in the back. This is a no-no in basketball. When a player's already committed to the dunk, that kind of contact is dangerous and unnecessary. You can see it throws off Risacher's balance mid-air, forcing him to grip the rim longer than intended. The mechanics of this play created a frightening landing that could have been much worse. NBA players know better than this - it's the kind of reckless play you see from someone who doesn't understand timing and safety on the court.
