The thing that I know is San Antonio Spurs were doing great last 2011. People were rooting from them and they were the team that wrecked all fans' preferences when it comes to basketball. But those were during their heydays. Nowadays, it's totally different. More teams have become competitive and the competition gets tougher! I don't think it was because the Spurs lost its magic. It's just that the other teams stepped up their game too and giving a good fight to each and every team.
