The NBA is retiring Bill Russell's number, but Hall of Famer Ben Wallace wants to see the league do the opposite on opening night ... telling TMZ Sports it would be awesome to have every player wear #6 in honor of the late Celtics legend.
As we previously reported, the league decided to permanently make #6 off-limits throughout the league after Russell's passing in July ... with exception of those who are already donning the digit, like LeBron James and DeAndre Jordan.
