Jimmy Williams can not compare with Dick Williams managerial accomplishments.
For you youngsters who weren't around in 1967, this is from an article written by Eric Aron for the Society for Baseball Research (SABR)
Dick Williams was regarded as one of baseball’s premier managers and turnaround artists. He was only the second skipper to win pennants for three different teams — Boston, Oakland, and San Diego.1 As a rookie manager in 1967, Williams led the Red Sox from ninth place the year before to the World Series. Both personally and tactically, he took a no-nonsense, aggressive approach, which electrified several teams that he managed. His A’s won back-to-back World Series, and he pushed the Padres to their first-ever postseason.
As a manager Williams compiled a record of 1,571 wins and 1,451 losses in 21 seasons, 20th on the career victory list as of 2014. Williams also enjoyed a fine playing career. As a versatile utilityman, he played with five teams in 13 seasons. After an appearance in the 1953 World Series with the Brooklyn Dodgers, Williams had three separate stints with the Baltimore Orioles, playing for manager and key mentor Paul Richards. Williams was voted into the Hall of Fame in 2008.
