Also, does the NBA truly have parity now?
Who won the ring this past season? NIkola Jokic.
A top 3 NBA player won a ring like they do nearly every season. The jersey has a different name, but the way it was won was still very similar to how it always is.
I dont know if you have some different interpretation of parity.
Parity in NA sports (by list of last 5 champions in each league):
NBA - Nuggets, Warriors, Bucks, Lakers, Raptors
NFL - Chiefs, Rams, Bucs, Chiefs, Patriots
NHL - Golden Knights, Avalanche, Lightning, Lightning, Blues
MLB - Astros, Braves, Dodgers, Nationals, Red Sox
MLS - LA, NY, Columbus, Seattle, Atlanta
So only 2 teams have repeated in past 5 years in NA major leagues, each of them once.
Non-parity in European soccer:
Premier League - Man City, Man City, Man City, Liverpool, Man City
La Liga - Barcelona, Real Madrid, Atletico Madrid, Real Madrid, Barcelona (last time anyone besides these 3 won was in 2003-04)
Bundesliga - Bayern, Bayern, Bayern, Bayern, Bayern
Ligue 1 - PSG, PSG, Lille, PSG, PSG
Serie A - Napoli, Milan, Inter, Juventus, Juventus
So 3 of the leagues have 1 team winning at least 4 of the 5 championships and only league that has apparent parity (Serie A) had Juventus winning 10 championships in a row before their run ended 3 years ago.
