End of game situation

[BigCat]

I'm with Rich that it isnt cut and dried..
I understand Decees position. The horn that blew wasnt just a horn that blows by mistake while time is running and left on the clock. It is the end of game or quarter horn. Does that mean the ball becomes dead at that moment (because no try in flight etc) and have to go to arrow? Or, because we know that horn shouldnt have blown and we know there is a half second left can we let play continue for what we say is a half second? Or in the OP give the ball to B for a throw in out of bounds because it would have been B ball there?

Say there is two seconds left on the clock in a tie game and A has the ball under their basket. They run a great play and A2 comes for a wide open layup. He catches the ball and the game ending horn goes off. CLEARLY clock was started early. Because it was the game ending horn does the ball become dead and A has to run another inbounds play with 2 put back on the clock? Or because we know there was 2 seconds can we let the play continue for the two seconds and then declare game over? Ignore that horn like we can other horns?

We know if the clock doesnt start when it should and we have a count we can take time off the clock. We also know if the timer stops the clock after a made basket we can take time off the clock based on our inbounds count etc. This is my nightmare scenario and why when it is a potential issue i always talk to the timer.....I tend to agree with Deecee and in my example A would have to take the ball out again if we went by rule. It is not cut and dry.....
