"The greatest team ever" is going to be the Montreal Canadians from the 50's and 60's. In a 16 year period 1953 to 1969 they won 10 cups (5 in the 50's and 5 in the 60's). If you add in the 70's that would be 16 cups in a 26 year span 1953 to 1979. The Kings have a long way to go to even be mentioned as "the greatest team ever".
