I was in diapers when "Loscy" played, but he may have been the meanest NBA player ever. He started a trend, which still exists today, of the superstar being protected by the enforcer. Maurice Lucas was one of my all time favorites. He had the meanest stare ever. When Darryl Dawkins threatened to create mayhem in the 1977 NBA finals, Lucas restored order in a hurry. It was the turning point of the series. Down two games to none, Portland came back to win four in a row, largely because Lucas shut down Sixer star George McGinnis the rest of the series.
EDIT:. Philadelphia was the team of my youth. And that 1977 team may have been the most star studded of all time, certainly for a team that never won a title. The ABA collapsed in the off season, sans four teams, and Philly scored specatularly in ABA free agency by signing Julius Erving. He rounded out a starting lineup that included Geroge McGinnis, Caldwell Jones, Henry Bibby and Doug Collins. Off the bench? How about World B Free, Bobby Jones, Jellybean Joe Bryant (who's son Kobe wasn't too bad himself) Steve Mix, Mike Dunleavy, Darryl Dawkins and Harvey Catchings. But a 70% healthy Bill Walton could do I all and Portland won the title.
