Love or hate the NBA (I’m in the indifferent category), he took it from a third-rate sport which didn’t even get live TV coverage of its final round championship series (and suffering from rampant drug abuse among its players), into the worldwide 7x24x365 media monster it is today.
Who cares?
Probably the greatest sports commissioner of all time, even better than Pete Rozelle because in the 60s & 70s the NBA was essentially what the WNBA is now.
