There are several reasons you see a chart like that. The first one is people turn on teams that win eventually. It happened to Chicago during the 90's. The other is the guys on the Spurs almost always act and play like guys with class. While very talented the guys in Miami have no done either of those a whole lot since coming together. Yes, I will give anyone that they've won a lot but if people can be honest they've not been terribly humble about anything. They've said multiple things that have just rubbed most people outside of Heat fans the wrong way. So people want to see them fail and rightly so. You can win, be hated, and still respected. Take the Yankees for example. A lot of people hate that team but respect the hell out of Rivera (retired) and Jeter. Why? Because they won with class and didn't shoot their mouths off. So all of that said is why you see charts like that.
