"They have the worst fanbase."
Here's one everbody hears about all the time, "Miami has the worst fans, they don't even show up till the second quarter and leave before it's over!" Granted that actually is the case some of the time, let's breakdown why that's such a horrible reason to hate on them.
LeBron and D-Wade aren't the ones in the stands, they're on the court making some of the best players in the world look foolish. Should the fans show better support? Without a doubt. Is that any reason to harbor anything against the team? Not at all. If anything, it should make you root for those guys for not getting the fans they deserve.
