Plenty of people hate on LeBron, D-Wade, and Chris Bosh for deciding to join forces in South Beach. What they seem to fail to realize is that the move, along with others like it, have made the NBA so much better. The idea of a Big Three isn't actually new, but it was revitalized by Miami, has generated genuine interest in the league, and has caused many teams to attempt the same.
Despite no other team having a comparable "Big Three," franchises like the Knicks, Lakers, Clippers, and Brooklyn have made attempts to do the same. There's no way the NBA would be as popular or interesting as it is now without teams trying to compete with Miami.
