Unsporting act(s) or ignore it/them?

[Rob1968]

Play discussed in a meeting last night:

Team A is leading by 1 point.
.3 seconds on the clock, clock stopped,
A1 oob for throw-in, guarded by B1,
A1 throws the ball off of B1's body, ball bounces on the court,
End of game horn sounds,
A1 immediately kicks the ball, forcefully, but it doesn't contact B1.

a) Several attendees insisted that throwing the ball off of the opponent was an unsporting act, and should have resulted in a T assessed to A1, and the subsequent free throws would have determined the winning team.

b) Some attendees said that kicking the ball should have been considered an unsporting act, with a subsequent T and free throws, determining the winner.

c) Some attendees said that the two acts combined, should have been considered worthy of a T, with free throws determining the winner.

I was the extreme minority, stating that if the throwing of the ball off of the opponent was not judged to be unsporting, that the kicking of the ball, after the horn had sounded, should be ignored. I cited CASE BOOK 10.3.6 SITUATION B.

I'm not looking for justification for my opinion, but will appreciate your discussion and responses.
