This is kind of cool, and kind of reminiscent of a project I did a couple of years back. CBS Sports is using Strat-O-Matic to run a single elimination tournament of the 49 past SB Champions. So far '97 Denver made it to round two, while the underrated and powerful '98 squad has made it to the sweet 16.

A couple of years ago I used the same game engine to run a 128 game elimination tournament. I might have to revisit that now that more seasons are available
