Just for clarity - I don't think the NFL should go beyond 20 games; whether by design, or accident, each sport seems to (eventually) find it's sweet spot. The AFL only added one round, but all are agreed that it's just about bang-on - so much so that there is already resistance to further, potential, change when Tasmania enters the competiton, in 2027. And the EPL dropped two rounds to get the League to a more European size (from 22 to 20 clubs), but remains the most successful sports league on the planet. At the end of the day, it's the quality of the on-field product which determines interest and success, not the length of season. - I'm sure many broadcasters would love to have more PL games, as they're going to get more CL games, under the new format.
