I've always found the coaching technical hard to rationalize.
Say your a coach and you want to motivate your players. You can do this in any number of ways: yelling at them, yelling at your assistants, yelling at the crowd, yelling at God for his cruel indifference to your suffering.
But only one of the options at your disposal might result in you giving the other team two uncontested points: yelling at the ref.
Of all the possible motivational tactics, only this one can have a directly adverse effect on your chances of winning the game.
Unless you truly can't control yourself—in which case perhaps you should try another line of work—why would you, as a coach, ever make a demonstrably angry gesture toward a referee? It's an obvious risk, with only hypothetical, intangible benefit.
My guess is that when coaches play these psychological games with officials they're only doing it to convince themselves that it works—in essence to exercise some control over (and insert their ego into) a part of the game they in no way control.
See that last foul call? If I hadn't called the ref a smoldering pile of human refuse that totally would've been a block. I'm an emotional genius.
Of course, it's not true. Refs are autonomous beings who have been specifically trained to withstand this kind of abuse. But coaches rail on regardless.
Anyway, Marquette coach Buzz Williams picked up a tech with his team down three against Georgetown on Monday. The Hoyas scored four points on the ensuing possession and the Golden Eagles never threatened from that point on.
With the loss, Marquette (17-6, 8-3) drops into a second-place tie in the Big East standings alongside—you guessed it—Georgetown.
