Everybody can have their own opinion. No doubt.
In life I've found that people tend to think that the heroes of their generation are the best.
People who grew up a few years before me are convinced that 70s rock is the greatest music ever created. They'll listen to Deep Purple and Zep and The Guess Who and so on and posit that all subsequent music paled. They also tend to think that Ali was the greatest ever. That vinyl was superior to digital. And so on.
I saw Jordan's career. The whole thing.
I've seen LBJ's career. So far.
LBJ has carried bums his whole career. The Cavs team he took to the finals (the first time) was a bunch of scrubs. When Jordan was playing with a bunch of scrubs, he had 3 straight first round exits.
ONLY after Pippen arrived did Jordan make it out of the first round.
It wasn't until several years later, when Pippen hit stride and averaged 18/7/6 and almost 3 steals a game, while shooting 52% from the field, that Jordan even made the finals! To most of the generation of fans who saw Jordan "save" the NBA and live a well-orchestrated life of sales that only was revealed to be a brilliant manipulation on the day he opened up at his induction into the HOF, he will always be the greatest ever, no matter what, because he's "Stairway to Heaven" when they were on the bus in the 9th grade smoking a joint and getting a handful. Jordan has always gotten too much credit for the rings, and Pippen has always gotten too little credit.
Swap Jordan for LBJ, and the Cavs don't make the finals this year.
Swap Pippen for Shumpert or Smith, and the Cavs bring home the hardware, even without Love or Irving or Verejao.
Jordan needed a top 50 player by his side to get to the finals. He had that top 50 player for all 5 rings and all 6 finals trips.
Dellavedova, Shupert, Smith, Mozgov. There have been 3,000 NBA players over the last 50 years. Do any of these players even make the top 500 of all time? Top 1,000?
Jordan is a sacred cow for people over 40ish. Just like Ali is for people over 50.
Further, LeBron doesn't care what people think about him. Jordan's whole public persona was molded and micromanaged by his agent. If Jordan had spoken his mind when he played, his legend wouldn't have been nearly what it is today.
