I find myself imagining the NBA of the future, when LeBron James is no longer the greatest star. It helps me appreciate what I’m seeing today. The last time I felt this way was the 1990s, when Michael Jordan was winning championships in each of his last six full seasons with the Chicago Bulls. Back then, everyone was very much aware of Jordan’s excellence. We were taking mental snapshots to remember him after he was gone. We were saying goodbye while he was still on top of his game.
