The Chicago Bulls were notoriously good at doing "the little things" that led to big wins. When they came to Utah to play the Jazz in the finals, the thinking was that they'd lose due to altitude (and it IS an advantage in a long series, even among supreme athletes). So Phil Jackson takes the team to a resort in Park City which is probably another 1,000 feet HIGHER in elevation. Plus it's 30 minutes out of downtown (not that SLC downtown is much, but still... it's a major city and has major city stuff happening nonetheless).
But the real key factor is that they went to 5,200 feet (or more) rather than the 4200 feet that is SLC and came in a day early and did workouts and such in Park City at this resort. Brilliant. They get down to SLC for the game and the elevation doesn't seem to bug them, because they are relieved to have just gotten a bit more oxygen. It was really smart then, and I think more coaches should think this way, but supposedly a "player's coach" never would think of this stuff. Whatever. Pete's a smart guy. Very smart. Atlanta is a trouble spot. That's a well known issue. But... you do the smart thing. You go somewhere like Phil Jackson took his Bulls, and you take care of business. If you lose... you lose. But it will not be because you screwed up on details that seem small, but can turn out to be massive.
