If you had to pick one team in sports who has historically been the most successful team of all of the teams in all 4 major sports, what team would that be? Its not an NFL team. Not an NBA team. Not an NHL team. Not a NL team in MLB. Not a MLB team in the AL West or Central. Not even the O's, Jays, Rays, or Bosox in the AL East. There is only one team left.
