Basketball has an 82 game regular season. After 82 games the Spurs were 15 games better than Memphis. Now the Spurs are headed home and Memphis keeps playing, if they somehow make it through and win the title game that makes them the best team around. Yup gotta love playoffs because it is decided on the court. The 82 games before apparently don't count as deciding it on the court. Again I say, Hooray playoffs.
(full disclaimer, yes I am a bitter Spurs fan at this moment but that doesn't change the facts of the situation).
