Which one has contributed more to basketball stats? I say Oliver. He's actually tried to enhance stats, whereas Hollinger just argues points he doesn't believe because he can, just to get a rise out of people.
Niether, I'd go with Rick Kamla. Hollinger is an idiot, IMO. He talks stats, I don't care. He makes idiotic predictions and he doesn't seem to have much knowledge about all the players around the league.
