Team/Player: Casey Stengel; Joe McCarthy
Date: 1949-1958 (Stengel); 1932-1943 (McCarthy)
As any coach or manager can tell you, winning a championship requires a unique blend of hard work, skill, and luck. It certainly helps, though, if you're at the helm of a really talented team that beats up on those that have not integrated African-Americans onto their rosters. Such was the case for Joe McCarthy and Casey Stengel, who both guided powerhouse Yankees teams between the 1930s to 1950s as they each netted seven championships apiece. Given how quick to fire managers most teams are and how quickly fortunes can shift, it's unlikely either would have stuck around long enough had the level of competition been better.
