The Physics of the "Eastbay": Originated by Isaiah Rider in 1994 and perfected in contest lore, the between-the-legs dunk requires swapping the ball from the non-dominant to dominant hand at the parabolic apex ($v_y \approx 0$).

Edwards' 42.5" vertical affords ~0.94s total hangtime, leaving a narrow ~200ms zero-g window to clear the legs and elevate above the 10-foot iron ring.
