Yeah, this guy's an idiot, and cites no stats to back anything up. It's refreshing to see how many of the commenters rightfully called him out on his convoluted nonsense. Here's my favorite comment, it is the author's rebuttal to all the other comments:
"Look, I know the Celtics put a ton of effort into their defense. I know they LOOKED like a great defensive team. And in effect they WERE a great defensvie team. But what I am saying is it wasn't from being great defenders. It was from having 3 great offensive players who complemented each other perfectly and together made the most efficient and potent offense in the league.
You take that tremendous unbeatable offense... put it on a methodical offensive team, like the Spurs, and you have the appearance of a great defensive team."
Hilarious - so we weren't that good defensively, we just had an amazingly good offense that also slowed the game down, so our defense LOOKED good. What's funny is this guy keeps alluding to the concept of defensive and offensive efficiency, but clearly hasn't bothered to look up any of the widely available stats on it.
