they actually broke 100 3 times out of 5
My mistake, sorry.
and when you consider that we were averaging 116 in the playoffs previous to this series and they held us to 104 - 12 points below our average - I'd say they played pretty damn good defense against a very hot offense.
Is your point that they played better defense than Memphis or Dallas? Sure, that's pretty evident. But the Suns still shot .496 from the field and .413 from three-point range, both above their regular-season averages. (These numbers are on suns.com.) There's no way that you can say that the Spurs played "great defense" if they gave up 104 points per game on those percentages. Heck, the Spurs didn't even force very many turnovers: only 13.4 per game, less than the Suns gave up in the regular season.
The Suns' offense was just fine against the Spurs. Because the games were slower, they didn't have as many scoring opportunities, but overall they were just as efficient as they were in the regular season, if not more so. Had the Suns rebounded at all -- they got beat on the boards by six per game, including four and a half on the offensive glass -- the series would still be going on.
"Defense wins championships" is a cliche, nothing more. If what people really mean is, "Overall superiority wins championships, and that includes being more successful defensively against your opponent's offense than their defense is against your offense, as well as rebounding well on both ends of the floor," then now we're talking about something substantive. But that doesn't have much of a ring to it, does it? So instead people say "Defense wins championships!" like it's some profound truth of the ages.
Well, it's not.
