We've dissected so many different angles but has the leaguewide parity of the last 5-6 years been mentioned much in the ratings discussion?
Thinking about it, the league's highest rated eras in recent memory were during the Bulls dynasty, Bron forming the Heatles and when we got Warriors-Cavs every year
As awesome as the parity has been for the purists and serious fans of the sport, it's the casual viewers that really drive the ratings and casuals historically love dynasties.
The more parity we've seen in the Finals and winners, the more the ratings have slipped.
Not saying that the league needs to legislate parity or anything like that at all, since I personally don't think the ratings are all that important big picture just yet, but they'll eventually need to do something to counter some of the prevailing narratives and perception of the league at large.
