Just warn him. When you get a chance say to him, "coach you are coming close to a line here." He probably will tell you, "I was talking to my players." Ignore that and if he keeps being sarcastic or disrespectful with backhanded comments, nail him. He will figure it out and change is behavior if he wanted to stay. But if you can stop the behavior without giving a T do it. But a much better official than me always told me, "when the roll the dice, they just might crap out." Just because other officials took his crap, does not give him the license or the right to disrespect you.

Peace
