In game pointers...

I'll admit right off that my statement isn't realistic but I'm going to make it anyway. Nobody should be working 4 games in a row - the brain just can't handle it, even if the body can. Watch a grade school tourney and notice how the best varsity officials are sucking up the place by their fourth, fifth and sixth games.

That said, mechanics are a great way to keep focused. Hold the ball the way you're supposed to during dead balls (toward the direction you're going), communicate fouler/shooter to partners, return signals on the number of shots, etc.
