Two Questions - 1) Punching the basketball and 2) Jumping off a teammate

[Gozer]

Not an exact quote ( dont have books on me try the last 1/4 of the book), but a player cannont use (come into contact with) any items or other players on the court to gain an advantage. ie screeners cannot hold hands and you can't boost another player. And most inportantly no RED ROVER on the court :P.

Take care hope this helps,
