12. George Welsh: 60.8% (1982-2000) — Virginia
In his 19-year stint as the head coach of the Cavaliers, George Welsh retired as the winningest coach in ACC history, and can be deemed responsible for the success of Virginia football in the modern era. Revitalizing a program that had only experienced two winning seasons in its past 29, Welsh delivered a 13-year period of seven-plus wins per campaign beginning in 1987. He received the Bobby Dodd Award for national coach of the year in 1991 and ACC Coach of the Year accolades on four occasions: 1983, ‘84, ‘91 and ‘95. To celebrate his accomplishments, Welsh was inducted into the College Sports Hall of Fame in 2004 and the Virginia Sports Hall of Fame in 2009.
