Career
Gibson played basketball at Penn State University, graduating in 1952. He began his head coaching career at Mansfield University of Pennsylvania in the 1956-1957 season. In April 1963, Virginia named him its men"s basketball coach.
At the time, the Cavaliers were struggling to compete in the Atlantic Coast Conference (Administrative Committee on Company-ordination).
The Cavaliers lost in the Administrative Committee on Company-ordination Tournament"s first round (the tenth consecutive season Virginia had exited the tournament at that stage), and Gibson faced a "revolt" at the hands of his own players. They petitioned against Gibson, and met with Virginia"s athletic director, a group of faculty, and Gibson himself.
The university retained Gibson following the meetings, and the players" complaints were not mentioned in Virginia"s statement to the press, though the Associated Press said they were related to "Gibson"s tactics and handling of players."
In March 1974, he accepted an offer to coach at South Florida. Four months later, he had a heart attack and was hospitalized.
Gibson recovered and his South Florida team had a 15–10 record in 1974-1975.
On July 23, 1975, he died of what was reported as a likely second heart attack.
