There have always been players in the NBA who are just better than everyone else currently playing. In the mid-1990s, Michael Jordan was that player who stopped a lot of superstars from winning the championship because he was just too good.
Superstars like Karl Malone, John Stockton, Charles Barkley and Reggie Miller were all victims of circumstance. If any of them had the slightest opportunity to win a ring, they could have.
But because of Jordan dominating that era, they couldn't.
I'm not going to make any player comparisons, but we are in the midst of experiencing a similar situation, but with the Miami Heat. LeBron James is the best player in the world right now and it's not even close, and his team has reached the NBA Finals for the third consecutive year in a row.
Perhaps we are witnessing an era where James and the Heat are in the same position as Jordan's Chicago Bulls. They haven't dominated the playoffs like the 1990s Bulls, but they are still the most dominant team in the league and have silenced doubters every passing round.
Unfortunately, that doesn't bode well for the rest of the superstars in the league. There are handfuls of great players who might not ever win a championship in this era, primarily because of the Heat's dominance.
