Honestly as someone who moves like a dwarf giraffe I always wondered why this did not happen as often.

Somebody accidentally stepping on the ball and rolling their ankle, somebody throws a pass too hard and it breaks somebody’s fingers, somebody tries to block a dunk and fingers get crushed between the rim and the ball, a shorter guy trying to jump for the rebound and his head hits a teammate/enemy’s chin/upper set of teeth, somebody tries to dunk but ball hits rim so he falls backwards because he can’t hold onto the rim, etc
