NBA Parity in the current ERA

When was the last time the NBA went this long without a repeat champion? No team has won back-to-back since the 17/18 Warriors.

Honestly I like the parity for now.

Potential reasons for parity:
1. League is more talented than ever
2. 3-point shooting can add more variance than ever in a single series
3. Injuries - so many injuries to key players during the playoffs.
4. This one is probably the most underrated reason, but team cap rules/contracts/free agency rules really impact any given era. Sometimes it's impossible to keep a good core together for more than a few years.
