How Long Can A Defense Stay in a Zone?

[SMEngmann]

Having refereed with the shot clock, I disagree that it leads to poor shot selection on the part of the players every time. Rather, the shot clock forces players to make decisions and work to get the best possible shot available within the shot period. Without the shot clock, you might be able to be patient enough to get a perfect shot opportunity (rarely are teams that disciplined), but that doesn't mean that teams don't get good scoring opportunities or rush every shot. The shot clock forces teams to be disciplined, especially in the way they use that time. I also think that the defense should be rewarded for doing a great job denying good shots. JMO.
