A pass is a pass, a shot is a shot...

I believe there are two ways for the alley-oop to be legal.

First, the pass off the backboard is a try. If it is judged to be a try, everyone knows why it is legal.

Second, if the player gathers the ball and establishes a pivot foot as in 4-44-3, the player can then release the ball on the pass before jumping off his non-pivot foot and dunking it.

I think case 4.44.3D(b) is considered a travel because the player (who has control and may establish a pivot foot) lifts both feet, restablishes the pivot foot and controls the ball again before it has touched or been touched by another player. This doesn't happen in the second situation above. The two actions allowed are a pass and a try. Both were done before either foot returned to the floor.

The release for the pass is legal and the neither foot returns to the floor until after the pass and try. If the player were to move his foot/feet in excess of the limits described in 4-44 it would be a travel as in 4.44.3D(b).

Someone help me decide if my logic is correct.
