The thing is is that the heat were #4 and lost to a #5 team, that happens all the time.  However, Dallas was #1, in the league as well, Dirk was named MVP, and they lost to a team that didn't qualify for the playoffs until the very last day in the first round, which is the first time a #1 team has lost to a #8 team in a 7 games series, ever.  Not to that fact but Nowitzki and dallas lost in the finals last year, didn't win.  Miami did, which means the pressure to win climbs insanely down, and its not like Shaq or D-Wade had great seasons this year to begin with.  Losing in the finals and improving your season the next year would increase the pressure insanely high.  On the other hand, if Miami were the ones #1, and D-Wade or Shaq were mvp, and they lost to Orlando in the first round, you would hear nothing of how they completely underperformed, and how its Shaqs fault for not controlling Dwight Howard, blah blah everything that Dirk is getting.  
And why wasn't Steve Nash to blame for his teams exit?  Just as you said, but also that Nash played extremely well, better than he did in the season, and if not for Robert Horry coming 'up big' again, and Nash's nose, its very possible the Suns could have won the NBA title.
But besides that, I thought it was a good article, mainly the end.  It did seem like the league 'wanted' miami to win.  (this wouldn't happen to have anything to do with Dirk being foreign by chance, could it?  Or for anything he's been getting) And I honestly don't blame him for losing in the finals.  I do however heavily attack him for this year, seeing that there wasn't really anything to say except he didn't show up when it mattered.  I do give credit though to Don Nelson to shutting down Dirk.(being his former coach might help though).  
I don't want to go on too long though(too late I guess).  Geeze, maybe I should have made an article instead.
