Examples

“Probably, [Sam] Perkins just wanted to get⟳ out of the way and not be "posterized," which is what happens when the dunkee is humiliated by the dunker. But [Michael] Jordan thought Perkins, his college teammate, would try⟳ to block⟳ the dunk, so he switched the ball from his right to his left hand at chest level. […] Jordan extended his left hand, and flipped the ball off glass, with reverse spin⟳, into the basket. […] Only one other such spectacular shot in a game of consequence comes to mind⟳, the time in the 1980 NBA finals when Julius Erving wrapped himself around the basket, going out of bounds while in the air in the process⟳, and posterized Kareem Abdul-Jabbar and Mark⟳ Landsberger with a reverse one-hand flip off the glass.”
