In Indiana, where AremRed and I are from, this is the #1 reason. Coaches have too much control on who works the tourney. Even if you Tech up a coach, they still can put a bad vote on you.

But can't they put in a "bad vote" for you regardless of you giving a T? The point is no matter what that seems like too much to worry about. Do your job and eventually the right people will respect you. Most coaches know why they got a T, even if they do not agree with you giving it to them.

To follow up on Jeff's comment: A long time ago a D1 official told a group of us newbies (less than 5 years), "They're going to be upset with you when you blow the whistle. They're going to be upset when you don't. Might as well blow the whistle."

Translation: You can't control what they do, only what you do.

and another one that a veteran assigner told us last year, "If the coach is mad enough to earn that T, he's not voting for you anyway, so you might as well give it to him"
