NC State -- Notre Dame end of regulation (Video)

I asked the same question. Pretty sure they missed that one. Should have been treated as a "dead ball" foul. In that case 2 other questions arise.
Not so sure but also wondering:

1) why did ND not get the ball under their own basket instead of under NCSt basket since NCSt never established control of the ball over half court at all?

2) Is it really an offensive foul or should that be considered a loose ball foul since it's up for grabs? In the case of loose ball foul ND would be shooting...

Finally - If ND had lost and we're right about either or both of the the first two questions, could they protest the game and get the last 1.8 seconds replayed?
