Soon after, White joined the New York Yankees baseball team; he served for a time as general manager of their minor league affiliate, the Richmond Virginians, before receiving promotions to the role of ticket manager in the late 1950s and business manager in 1960.[4][5][8] By 1963, his position had become "director of baseball scouts".[3] He ultimately served with the Yankees for 25 years.[2]
White also began working for the San Francisco 49ers of the NFL as a part-time scout in 1951.[4] He was promoted to director of scouting in 1965, and two years later was named the team's general manager.[4] He helped the team win their division three straight times from 1970 to 1972 as manager, before accepting a role as vice president of player personnel in 1973.[4] He retired following the 1976 season.[4]
The San Francisco Examiner writer Al Corona described White's football career: "He negotiated with all these guys. All the contracts went through Jack. The players liked him. He kept to himself mostly. He was just a nice guy and knew football well."[4] 49ers executive Louis Spadia noted White was "one of the most experienced and able men in the game in the area of seeking out and evaluating football talent."[4]
Later life and death
White moved to Oregon after retiring and enjoyed raising horses.[4] He was married and had two children.[4] He died in White City, Oregon, on September 26, 1997, at the age of 84.[4]
