Super Bowl Suspicions: Scripted or Legit? Will Chiefs Versus Eagles Break the Pattern?

This is just an observation.
Reviewing the winners of the Super Bowl reveals a curious pattern.

Every decade one specific team emerges victorious in three Super Bowls. Statistically, this pattern is virtually impossible without some form of intentional manipulation. In other words, a calculation of the probability yields odds that are astronomically unlikely.

Strange that not one decade has passed without one team being chosen as the winner of three Super Bowls.
What message is being conveyed?

While two teams, The Pittsburgh Steelers and the San Francisco 49ers, have back to back Super Bowl victories at the end of the decade, which seems to discredit this pattern, these Super Bowl appearances result from a regular season that occurred within the prior decade: the Super Bowl itself fell outside the pattern.

This suspicious pattern raises an interesting question in regard to this year's Super Bowl: Will the Chiefs win the fourth championship in the 2020's, disproving or breaking this pattern?
A betting man would say no. But only time will tell.

Steelers: 3 in 70’s
49er’s: 3 in the 80’s
Cowboys: 3 in the 90’s
Patriots: 3 in the 00’s & 3 in the 2010’s
Chiefs: 3 in the 2020’s
