Just like last year I prefer the Spurs winning the championship over the Heat. Of course I prefer the Spurs' playing style, and think that Duncan deserves that Duncan deserves another ring. Of course that the Celtics' loss against the Heat in the 2012 Conference finals still hurts. Those are all great reasons for wanting the Spurs but let's think what scenario would benefit the C's more.
I don't think It's good to have one team sitting on top for such a long while. I mean, this is the Heat's fourth consecutive Finals appearance! Success should flow freely from one team to the other, competition is good! If the Celtics will be able to rise into contender status over the next few years we don't want the Heat to stay so powerful and with that much momentum. This why it is very important that the Spurs win, and that the Heat will face some adversity.
If you have a different opinion or have more reasons why the Spurs should win i'd like to hear.
