Like I said previously, I'm still trying to get my head around this one too...
48 hours ago, I would have agreed with you. However, it now appears to me that tossing the ball off your own backboard is ... nothing. The rules acknowledge it, and tell us a little about this activity (e.g., it is legal, it is not part of a dribble). But that's about all they say about it. Trying to fill that void by shoehorning this action into another rule which regulates a different activity is incorrect. You may as well argue that the thrower moving from the designated spot is traveling, it's the same (incorrect) logic.
Without posting all of the relevant text...
Traveling is moving beyond the prescribed limits while holding the ball. There is one exception, and that involves placing the ball on the floor while getting up.
Dribbling involves pushing the ball to the floor. The opponent's backboard is considered part of the floor for this purpose. One's own backboard is not. It is simply "equipment".
Passing involves another player, or at least the intent to throw the ball to another player.
And we acknowledge that we're not talking about a try.
So what does that leave? It leaves an activity that is not regulated by rule.
As for the "self alley oop"... the NCAA case book says this is legal and is a try. The NFHS case book does not actually say this, but there is a case situation that is close that is deemed legal. It is activity that is otherwise widely accepted to be legal. The rules do not prohibit it.
Camron has suggested that the "self alley oop" is actually two tries. I'm not convinced, but I have no basis for argument. I think the whole process of throwing it off the glass, catching, and dunking constitutes one play and is therefore all part of the same try. But I have no basis for my argument either.
My personal feeling on the whole subject? I'm putting away my shoehorn.
