Fate plays a big role in SB winners, I believe, but not just on the side of "footballness". I am a big believer in the underneath character and nature of people and how this fits with what the higher forces expect from a winner, especially in America.
American winners are somehow expected to be leaders in true class and character. I believe the Pats of 2001-2004(5) led in that category and therefore could win the three SBs.
The real test comes after early success: the lower forces of selfishness are just crying out for appeasement, but the forces for unselfishness must overcome that temptation.
I've been following pro sports for some 40 years and that trend has become clear. Dynasties like the Celts, the Yankees, the Canadiens, the Edmonton Oilers, etc., all had a certain quality of unselfishness among the players. The moment they lost that was the moment they went down to the level of "average team", where self-centered goals are more important than team goals.
Character is king, and fate observes that scrupulously.
