From the responses on the the first situation I'm still not clear on exactly what is the correct way to handle this. Since our game was a blow out we discussed the issue with the coaches and neither had a problem with the switching of the jerseys so we went on without any problem.

Second situation, I have a better idea of what I think should have been done. I think that we really should have shot two with the lane cleared whether the foul happened before or after the horn, because A1 was an airborne shooter the whole time. Not sure if I read this on the board or in the rule book so I don't have a reference but in a similar situation where the shot is released, horn sounds and then A1(shooter) gets fouled after the horn before he returns to the floor we would still call that foul correct? Isn't this the same type of situation except that the ball was released after the horn?
