I found this interesting: ]Had the Braves not left in 1953 for Milwaukee it is quite possible that in a few years they would have become more popular than the Red Sox as they went on to win 2 pennants and a World Series in Milwaukee led by a young slugger known as Henry Aaron. Today we might be fans of Boston Braves Nation. A similar quirk in timing affected Philadelphia. For so many years, the Athletics were the dominant team in that city, but at the time that the first wave of franchise moves hit in the 1950's, the A's were in a downturn and the Phillies had recently won the 1950 NL Pennant. And I remember reading that Bill Veeck was jockeying for the Browns to get the upper hand in St. Louis at that pivotal time, in the hopes that the Cardinals would relocate and he'd have the city all to himself. (That effort, obviously, failed. He probably never really had much of a chance.) But if the Braves had stayed in Boston, and the Red Sox had gone to Milwaukee, or Kansas City, or wherever, I imagine that the Pirates would have gone to the NL West in 1969 (the Cubs and Cardinals were insisting that they stay in the same division) which would have certainly made the early years of divisional play much different. The 1969 race would have featured the Mets, the Cubs, and the Braves, who won the NL West that year. And the Pirates ended up winning the NL East five years out of six starting in 1970. If they were in the West instead, they might have taken some of the steam out of the Big Red Machine and cleared the way for some lesser teams to compete in the East during those years.
