need rule numbers? for clarification

[jritchie]

couple of us here at work are talking about a couple plays..
no books available at the moment..

1)throw in under basket, ball is thrown towards basket and hits the backboard before touching anyone! (Bottom or side) Legal or not?? Rule reference please!

2)player A1, throws ball in to A2, A1 comes of screen from out of bounds and gets a return pass....player A1 only had one foot down in bounds and the other foot has not touched in bounds yet, but is in the air when the pass came back to him..is he considered in bounds or does he have to have both feet down in bounds before he can get the return pass??? rule reference please!!


Thanks
