Why are the Spurs so Good?

So, I've never been a fan of the Spurs.  To me, they've always been a boring team to watch.  Slow, methodical, defensive, fundamental...etc.  (Not to mention they have Manu Ginobili, one of the biggest floppers and fakers in the NBA.  Must be an Argentinian thing...)  But they've been a very good team for a long time.  Probably because of all those things I just listed off.  But this year they are super good.

At them moment (I say at the moment because they are playing Miami right now, and all of this could change) they are leading the NBA by 6 games over the nearest competitor, Boston.  That is a huge lead this late in the season.  They rank in the top 10 in PPG, APG, and RPG, and 12th in the NBA in points allowed per game, which is really strange because their offense seems to be better this year than their defense.  For awhile they were on pace to match 95-96 Bulls with the best record in NBA history at 70-12.

So why are they so good?  I look at that team and I see a bunch of aging stars.  Players past their prime.  Tim Duncan is 34 for crying out loud and in his 14th season.  Ginobili is 33, Richard Jefferson is 30, and Tony Parker is a little younger; he's 28.  But then again, maybe that's it.  The main 3 players, Duncan, Parker, and Ginobili, have been playing together for a lot of seasons, and there's something to be said for that kind of experience.  Also, there's no "Big 3."  There's no big hype around the team, leading to very few distractions.

Normally these kind of things would make me a fan of the team.  But there's something about the Spurs that I just don't like.  I'm hoping that this jinxes them tonight against the Heat, so that they can't tie the Bulls for the best record.
