The NHL and the MLB retired numbers
I dont see why the NBA shouldnt
I wonder what LeBron would wear
The NHL retired a jersey of a guy who was by far the most dominant offensive force in NHL history. He broke every scoring record in the NHL. Only one player even had seasons that were close to Gretzky's and that was Lemieux. 9 of the top 11 scoring seasons in NHL history are held by Gretzky. Lemiux holding the 5th and 9th spot.
MLB retired Jackie's # for obvious reasons.
While Jordan was dominant, his dominance was not on the level of Gretzky. The #'s Jordan put up have been seen before, and will be seen again. The #'s Gretzky put up, were never seen before, and will probably be never seen again.
