it's actually the opposite...
This ain't like the NFL where u can win a superbowl and then not make the playoffs the next year. In the NBA once a team is championship level they usually make it again or win it again very soon. This league has been full of repeat champions for a long time.
the only franchise that has repeated in the past 12 years is the Lakers.. and that was two seperate runs
stockton and malone were well into their 30's when they made the finals. thunder starters are barely legally drinking.
