Jack Edward O'Brien (born October 21, 1932) is an American former college and professional football player who was an end in the National Football League (NFL) for three seasons during the mid-1950s. O'Brien played college football for the University of Florida, and thereafter, he played professionally for the Pittsburgh Steelers of the NFL.
O'Brien was born in Jeannette, Pennsylvania in 1932.[1] He attended Jeannette Senior High School,[2] and he played for the Jeannette Jayhawks high school football team.
O'Brien attended the University of Florida in Gainesville, Florida, where he played for coach Bob Woodruff's Florida Gators football team from 1951 to 1953.[3] In an era when college football rules allowed only limited player substitutions, he played both offensive end and defensive end, and was rated as one of the Gators' five best ends of the 1950s by coach Woodruff.[4] O'Brien was a junior starter for the 1952 Gators team that posted an 8–3 record and defeated the Tulsa Golden Hurricane 14–13 in the 1953 New Year's Day Gator Bowl—the first NCAA-sanctioned post-season bowl game in Gators history.[5] Together with running back Rick Casares, he was a senior team captain in 1953.[3] Woodruff later ranked O'Brien as one of the Gators' five best receivers of the 1950s.[6]
After his NFL career was over, O'Brien returned to Gainesville and graduated from the University of Florida with a bachelor's degree in physical education in 1958.
The Pittsburgh Steelers selected O'Brien in the seventh round (seventy-ninth pick overall) of the 1954 NFL draft,[7] and he played in thirty-one games for the Steelers during three seasons from to .[8] In an era of run-oriented offenses, O'Brien made the most of his few catches—he had sixteen receptions for 185 yards (an average of 11.6 yards per catch) and two touchdowns.[1]
