My guess.

No contact. Violation, warning, or technical foul, if already given one of the four delay warnings. However, if the throwin is successful, I might chose to ignore it, and speak to the offending player about it. I won't ignore it a second time after speaking to the offending player.

Contact. An even better question. I still say intentional personal foul if the throwin hasn't ended, by the above definition.

That's my story and I'm sticking to it. What's your story?

I think that you should take a hard look at 9-2-10.
