Good point. Really enjoyed those Tampa (47th largest city in America) & Pittsburgh (#68) championships. Two small market teams overcoming the odds to win it all. Heartwarming.
The notion that baseball has "an indisputable amount of parity" is just nonsense. The local TV contract money assures this isn't the case.
I listed two small market teams that won in the NHL. You've got to go back to 2015 (Kansas City) to find a World Series winner ranked that low. Throw in St. Louis and you've got two in the last 10 years. Of course the Blues won a Cup in that timeframe, yet another small market team succeeding.
