If A1 is going towards the basket, holding the ball, D1 got his hand on the ball so A1 couldn't launch the ball, if A1 still holding the ball all the while when he landed i would assume it's a jump ball, but what if after D1 touches the ball, A1 let go of the ball, would A1 be legal to grab the ball before anyone else touches it since A1 is still the last person to touch the ball:

a.Before he touches the ground
b.After he touches the ground
