How Far is Too Far?

[Brad]

You suck.
Are you blind?
WHACK!!!

That call sucked.
That was a garbage call.
Not automatic as above. When a coach says "you" it takes on a different tone. "That call sucked" is not the same as "You suck"

I'd judge the above based on what has gone on the rest of the game... If nothing so far then address verbally, if you have already addressed give the official warning -- past that maybe WHACK maybe ignore -- take the game situation into account.

Quietly within earshot of no one but me in a non-hostile tone: "Geez, Spence, that was a B.S. call."(without using the initials)

Probably not for me... Again, I would take the rest of the game into consideration. If that coach hadn't said much then this would probably just get a warning. If there had already been history this game then it might be a tech.

Without even having read the rest of the thread other than the OP, I'm sure that many will say WHACK everything, but I think that we need to always consider our full range of responses rather than be a one-trick pony.
