Throw-In ends, huh

[RushmoreRef]

That's for a lodged ball, yes...

This ball only touched the floor and went oob...or didn't touch the floor.

My point is according to rule 4.42.5:

The throw-in ends when the passed ball touches, or is legally touched by, another player who is either inbounds or out of bounds.

In situation posted the throw in never ends by a touch.

So, does rule 9.2.2 mean it is a violation to throw a ball in that doesn't touch anyone and proceeds to go oob?

I feel really dumb on this one....don't beat me up too bad.
