Use of own backboard (not a try)

[HawkeyeCubP]

I feel that the issue here centers around the use of one's own backboard. To get into the definition of a pass and whether or not an official judges the ball movement in these cases to meet that or not is irrelevant, as the case plays in all rule sets clearly state that it's not a violation to throw the ball agains one's own backboard (some of which then go on to say the thrower catches the ball). The issue, as Adam has stated, is whether it matters that the ball, when thrown off one's own backboard, comes back and is touched or caught by the thrower who is either still in contact with the floor or not.
