Indianaref wroteSo I quess it's alright for A1 to stick the ball on the hip of A2 and run down the court?
Nah, as even if this slips through some loophole in the rules; I think it's safe to say it's an advantage not intended by the rules. If A1's purposefully sticking the ball on the hip of a teammate, I'd consider that control.
No offensive player in his right mind would do this with an opponent's hip on purpose; dribbling is both easier and more controlled.
Besides, it would just be easier to dribble and use A2 as a blocker. 😀
