O'Brien was a three-year Boston College letterman (1968–71) while playing for Bob Cousy and Chuck Daly and he was team captain in 1970–71. He still holds the school single-game record for assists with 18, vs. Le Moyne December 16, 1970. He scored 1,273 points, a total that ranks 14th on the school's all-time scoring list. He twice won all-East honors and was the New England Player of the Year as a senior. He was elected into the Boston College Varsity Club Hall of Fame in 1976, his first year of eligibility. He also has the unique honor of being named to two Boston College all-decade basketball teams (1960s and 1970s).
Upon graduation, O'Brien was selected by the Buffalo Braves (today the Los Angeles Clippers) in the fourth round of the 1971 NBA draft, but he instead played professionally for the Pittsburgh Condors (1971), the Kentucky Colonels (1972–73) and the San Diego Conquistadors (1974–75) in the American Basketball Association. He played for Wilt Chamberlain at San Diego.
