If you think MJ changed the NBA than Allen Iverson revolutionize it. A.I was one of the first NBA players to get tatted up now 13 years later everyone he is calling it a career. Dont forget that everyone in the league has a tattoo thanks to A.I. Honestly I dont think that he is going to stay retired for long. Those injuries finally took a toll on him and he taking a little break. If anything he should go back to the Denver Nuggets and try to win a Champ.
