Last season, LeBron James missed more than seven games (13 actually) for the first time in his NBA career and finished with his worst scoring average (25.3 ppg) since his rookie year. Were those the first signs of decline for the four-time MVP? Time will tell, but if that’s the case no one should be surprised considering the mileage on his body. At just 30, James has played more minutes in his pro career than many NBA legends. Combining minutes logged in the regular season, playoffs and FIBA competitions, he is already ahead of Magic Johnson, Larry Bird, Jerry West, Clyde Drexler and Steve Nash, who played his last game at age 40. He will likely surpass Charles Barkley, Patrick Ewing and Oscar Robertson next season.
