This comment interested me, so I did a little research.
Not including meaningless preseason games and USA Basketball games(not meaningless), Lebron at the age of 31 years old, has played 46,861 minutes. Jordan at the same age played 31,575 minutes.
Now obviously Jordan played 3 seasons at UNC, had the ankle injury his second season, and was suspended for gambling, so obviously MJ's number is going to be lower. My only point being that Lebron has put on A LOT of miles on those legs. Obviously a genetic freak of nature, but my new thing going forward with Lebron is going to be how he manages his minutes during the regular season from here on out. That may have actually already started, btw, as this was his lowest MPG for the season in his career.
