Mockery or not

[SAK]

AAU woman's tournament today. Team A was leading by about 15 points with under 2 minutes to play. Team A decided they were not going to play defense and only play offense. In obvious disgust for his team's inability to play defense (all of a sudden) the coach of team A instructs his girls to throw the ball out of bounds every time they have possession of the ball. So team B would score, team A would inbound the ball and immediately throw the ball out of bounds. Team A's coach then instructed his team to play defense. This repeated until the end of the game.

Team A still won the game but was coach making a mockery of the game deserving a T or are other officials ok with this tactic and say play on?
