2. We note that some teams have changed their names over the years. So, when referring to a specific season, we use the team name that was current during that season. Hence, you might see a reference to the 77 Boston Bees teams when making a reference to 1936, even though the team had other names before and later, finally becoming the Boston Braves until moving to Milwaukee.
