You are right,I didn't find.But normally a player must take part to a Hall of Fame when he realised the great performance in the club,not after years after other players could repeat that performace.
And now I have a question.Why Buzzerbeater.org allowed to add active players in Hall of Fame?!
That is a question for BB staff not for me.
And it is not a question if someone can repeat his performance.
After some time there will always be someone that will repeat or have even better performance than him, but he made his mark at that club, and retiring his jersey shows how much club appreciate him and what he has give to that club.
BUT NO ONE DO THAT WHILE PLAYER IS STILL ACTIVE.
NO NBA, NO NFL, NO NHL, NO MLB.
Chicago Bulls retired no 23 when Jordan decided to leave basketball for first time. Than he decided to come back and he choose no 45 for that season. But very next season they gave him his 23. It is stupid to have jersey on cealing with name Jordan, and that same Jordan is still playing, as a matter a fact on the same court.
