Just to clarify my earlier posts on the subject; there are typically two type of whistles. 1) infractions resulting in a foul (a push, a grab, hit on the arms, etc), and 2) infractions that result in a turnover (step out of bounds, 3 second call, moving screen, drag a pivot foot, etc.). I want to see officials adopt a "tight whistle" on type 1 infractions, and a "let them play" whistle (non-whistle) on type 2 infractions. With consistency being an obvious common denominator. Why? Because, unless it is obvious, the refs would need to run around with rulers and stopwatches to get the type 2 infractions right. Furthermore, type 1 infractions often cause a type 2 infraction. For example, a player gets the ball underneath the basket and gets bumped out of bounds, is it a foul or a turnover for stepping out of bounds? Because 1 can cause the other, type 1 infractions should have priority and be called "tight". IMHO. BTW, this is how they call it in the NBA and while not perfect, I prefer that.
