A Few Questions

[bob jenkins]

The key to these rulings is that a ball hitting the backboard (other than the back) is the same as hitting the floor inbounds, except that hitting your own backboard is not the start of a dribble.

So, (IIRC the questions correctly):

1 a and b) Neither of these are violations. IF the ball hits the back of the backboard, that's a violation (the back is out of bounds).

1c) A throw in must be touched first (or touch) by someone ohter than the thrower.

2) Not a violation.
