I find the yearly ranking element interesting:
(32%, 29%, 23%, 16%).

On simialr efforts, using a fraction to the exponent of years produces a neat result:
For instance 1/2^year would be (1/2, 1/4, 1/8, 1/16 or 0.50, 0.25, 0.13, 0.06)... This weighting tends to favor last year's performance heavily with a quick roll-off on history. The neat thing about it is you can use all of history and still not hit 1.0. The bad thing about it is that past 4 years has very little impact.

Using (2/3)^year gets 0.667, 0.444, 0.296, 0.198 which normalized to a sum of 1 would be 0.417, 0.275, 0.185, 0.116. Using this algorithm tends to favor teams with longevity ans consistent high performance, but can also keep a team in the spot-light possibley a year or two after their prime if they have a very strong legacy.

A correlation study would be interesting to dig into.
