My guess is that if he's that irritated with his players, he probably gets irritated quickly with the refs. If so, it shows he's out of control. If not, well, I'm not sure it's not worse if he's doing that under complete emotional control. Something tells me it's all controled, but that's only a guess.

Either way, I'm with Julie, I'd be inclined to ring him up for tossing a clipboard; even if it's obviously in disgust at his team, it's middle school. I don't think it's any different than if he swore at them for all to hear.

He's taking a risk by doing that, that the refs aren't going to think he's tossing the clipboard in disgust at them.
