The thing you have to remember is that most people in the world are stupid. That explains why ratings are down for the Spurs. True fans of basketball will just laugh at that and think, "WTF? Really? The Spurs are awesome to watch."
I don't want to make the argument that anyone who doesn't like the Spurs is stupid. That would be a fallacy. But I do argue that the lack of popularity for the Spurs is largely attributable to stupidity.
