end of game, scoring a bucket for the other team

[Texas Aggie]

Not sure I understand the question. Are you saying Team B, ahead, scored at A's basket so they could have the 5 second count throw in and run out the clock? If so, this is a non-issue since you stop the clock when team B scores at A's basket. Award B a throw in allowing them to run the baseline. No need for a T here and this doesn't allow them to gain an unfair advantage.
