Jim O'Brien

James M. O'Brien (born November 7, 1951) is an American former professional basketball player. O'Brien played college basketball for the Maryland Terrapins, leaving as the program's sixth all-time leading scorer. The Indiana Pacers, then of the ABA, selected him in the third round, He played semi-pro ball for Trenton in the Eastern League for a few months while getting paid by and practicing with the Nets.

The Nets cut O'Brien during 1974 training camp and he was signed by the Memphis Sounds. O'Brien said of being cut by the Nets that: I had the feeling I was going to be cut in camp. I thought it was between Al Skinner and me but when Ed Manning arrived and got the playing time I knew I was gone. I didn't panic though. I thought there was a place for me and I am very happy here in Memphis. I'm getting the playing time and I don't care if it's at guard or forward.

The Sounds folded after the 1974–75 season and O'Brien signed with the Cavaliers of the NBA, despite having an option year left on his ABA contract. O'Brien was waived by the Cavaliers before the 1975–76 season started.
