You don't see much of what I'd call 'practice shots', although,
every so often, you might see a guy try 3 or 4 of the same shot.
Mostly, they just seem to be getting loose - getting the feel
of how the ball is moving today. But, is there more?
I had a friend who was convinced that the biggest loafer (or most disinterested) during the warmup was going to be the winner. He didn't say that in a way to suggest the outcome was prearranged, only that the 'loafer' might be conserving his energy or, like Brer Fox, just "layin' low".
