In the early 1970s, there was chatter about the White Sox possibly moving away from Chicago. Then Dick Allen won the MVP in 1972, and those rumors subsided for the next few years.
By Baseball-Reference's WAR, Allen's 1972 season was the second-best ever put together by a White Sox player. Only Eddie Collins (10.1 WAR) had a better season for a position player, with that coming in 1915.
Think about that. Only one position player in White Sox history has ever had a better year than Dick Allen had in 1972. It's one of the 75 best seasons for an American League player and is in the top 150 for any league all-time.
No wonder he helped save baseball on the South Side.
