Certainly there is no disputing that The Evil empire, the Yankees, are the greatest Baseball team of all time: mostly because they can always afford to be....... Starting with the buying of the greatest baseball player of all time, Babe Ruth, from my beloved Red Sox.
Football is certainly the Packers, with their long history of Championships over many decades, compared to the Steelers.
Basketball is easily the Boston Celtics with 17 Championships over the LA Lakers with 11. Chicago would be third, with six?.... and the Minneapolis Lakers of the white ball era of the primitive 1950's, with five, a distant fourth.
In hockey, which is a second tier sport in this country, but not Canada, it is easily the Montreal Canadiens.
They are to hockey what the Yankees are to baseball. There is not even a close second, as in football and basketball.
