A three sport letterman over five years at the Hilltop, Jack Flavin was one of Georgetown's most distinguished athletes of his day.
Flavin began his career on the basketball varsity in the 1918-19 season, playing in six games and averaging nine points for a team which scored, on average, only 37.2 per game. He won a starting role in 1920 alongside Fred Fees and Andrew Zazzali, and took over Fees' scoring in 1921 by averaging 12.5 points in 1921, or about a third of the team's offensive output.
"Speedy as a greyhound, he could flash in from back court, take a swift pass, and ring up two points before his guard could see him," notes the 1921 Ye Domesday Booke. "He could drop them in from any distance with good regularity, and his clean cut shots have made for him as good a reputation on the court as he enjoys on the gridiron."
Flavin was moved to second forward in 1922, where Paul Florence was named designated free throw shooter and took the scoring crown, with Flavin's 7.2 average a close second. Flavin was a star across three sports: an all-South Atlantic halfback, a third baseman on Georgetown's 1922 national championship team, and an expert basketball marksman.
He completed a fifth year in 1923 before the University, perhaps growing uneasy with Flavin's academic progress, ended his eligibility.
After Georgetown, Flavin moved to Buffalo for a two year run in the NFL, followed by a season as the head coach at St. Bonaventure, compiling a 13-5 record.
Jack Flavin was enshrined in the inaugural class of the Georgetown University Athletic Hall of Fame in 1958.
