No one “wants” parity - but we all bitch when it’s not our team doing the winning.
Fact - look at viewership of the respective sport when Yankees were willing WS year after year, Bulls were dominating NBA and UNLV was the dominate NCAA team.
Only “dynasty” I can think of that didn’t command a huge share were Oilers in the 80s - Gretzky of course got the press - but look at those teams.
Today it’s anyone’s trophy most years - and it sucks. Even when a team like Chiefs or Warriors start to look dominate - we are plotting their downfall.
