Brought up in the town where basketball was invented, the son of Irish immigrants, he worked his way through law school by tending bar in his father's cafe in the daytime and taking classes at night. One of the most trusted of politicians, known for his uncommon organizational abilities and his gift for compromise, O'Brien is a fascinatingly long-winded conversationalist who speaks with many digressions. "The sports commissioner is somewhat unique. First of all, you are paid by the owners, and you are expected to be as responsive as you can to the fans -- to do everything possible to ensure that the game is presented in the best conceivable way to the fans, and the most exciting and interesting manner, because after all, this is business." During the Kennedy and Johnson White House years, he served as presidential liaison to Congress and helped win passage of the Peace Corps, Medicare, and the Civil Rights Act of 1964. As commissioner, his authority is all-powerful. "It goes to supervision of every aspect of the game, on and off the court," he explains. "It goes to determining even what time games are played and who plays them." Attendance in the NBA has risen considerably this year; O'Brien cheerfully attributes it to the resurgence of the Boston Celtics and the improvement of the New York Knicks. Recently Dallas was granted a franchise to create a new NBA team, the 23rd in the U.S. "If there were further expansion beyond 24 teams," O'Brien predicts, "I think it would take on an international flavor. ... There are a number of countries in Europe that are playing quality basketball at the professional level. I envision that by the mid-80s, you would find countries in Europe that could be competitive with us. Probably the first step would be only exhibitions, but I can see it reaching a point where you could give serious thought to establishing another conference perhaps." Larry and his wife Elva have been married since 1944; their son Laurence III is a Washington-based lawyer. An Eastside resident during most of the last seven years, O'Brien recalls the Watergate break-in with grim humor. "We didn't have anything in the office anyway. We were practically bankrupt. I thought, maybe there's a typewriter missing. ... I was a disbeliever. It took a long time for it to penetrate that this was real. ... My best recollection of that period is that I was very depressed, in the sense of what effects it was having on our system of government. "When I was on my book promotion tour, people would ask, 'How does it feel to be a politician?' as if it was a dirty word. I have always been proud of being a politician, and I've never felt otherwise. But I found that all of us involved in politics were painted with the same brush."
