Now I am wondering if I called it correctly.

[Hawks Coach]

To give an example why you might want a technical. A has ball and lead with time running out. B's coach wants a foul, B1 is oblivious. B2 runs over and gives a tremendous shove to B1 who crashes into A1 and sends both to the floor. If B2 made contact of this nature, you would have an intentional foul - two shots and ball. But B2 didn't make the contact and B1 fell into A1 - hardly grounds for an intentional.

Simple answer is T up B2 for the shove, ball was dead at the point of the shove, the foul never happened, A gets 2 shots and ball. Gets the right result and actually seems supported by rule to me.
