American LOVE playoffs (to the point where the regular season is a long, cruel joke - see NBA, NHL). But other sports crown their champions based on their overall record over an entire season. For example, in the European football = soccer leagues (e.g., Premier League, La Liga, Bundaliga) the title is decided by overall record. In those leagues, every team plays every other team twice: home and away. The winner of the league cup is the team that has the best overall record. That does limit the size of your league. The soccer = football leagues spice up the title race (best teams) with the race to the bottom too. The bottom 2-3 teams are relegated to a lower league and the top 2-3 teams in the lower league are promoted to a higher league - billionaire American owners (and fans) aren't going to vote for a relegation / promotion system...
I loved it when the PAC-112 was small enough that every team played every other team in the league, especially in basketball - home and away; the team with the best record was the champion.
