Maybe it's a bizarro world where the commissioner of the most popular sport on the planet is concerned with the long term viability of the sport, therefore promoting modest, even handed enforcement only when necessary and promoting the safety of players by researching soft helmets, and avoiding unnecessarily long trips to other continents, and games with less than 6 days rest in between, to ensure future profitability by maintaining a high level of competition.
This bizarro commissioner even believes that people tune in to watch excellence and championship play regardless of parity in a given time period.
