A league divided into two conferences is running two partly separate competitions that meet only at the end. That structure decides far more than travel.
Conferences exist to control travel
Geographic splits developed because a national league cannot have every team fly the width of the country repeatedly across a long season.
Playing conference opponents more often keeps most trips short. The schedule is built around that principle before anything else.
The consequence is that no two teams play the same schedule, which is the root of everything else the structure causes.
Unequal strength produces unequal paths
Because teams are assigned by geography rather than by ability, one conference can be substantially stronger than the other for years at a time.
A team in the weaker conference reaches the final round with a lower record than a team eliminated earlier in the stronger one.
Nothing in the design corrects this, since seeding is done within conferences and the two brackets never interleave.
The bracket rewards seeding within a conference only
Home advantage in the earlier rounds is awarded on conference position, so the value of a good record depends on the company a team keeps.
Winning fifty games is worth a high seed in one conference and a middling one in the other, despite identical performance.
Leagues have partially addressed this by seeding strictly on record within a conference rather than protecting division winners.
Reseeding proposals keep returning
The obvious fix is to rank all teams together and build one bracket, which would guarantee the strongest sixteen teams enter.
The objection is travel. A cross-country first-round series in a best-of-seven format adds flights in a schedule already dense with them.
Partial proposals reseed only the final rounds, keeping early-round travel local while ensuring the last matchups reflect the whole league.
Conferences also structure everything administratively
Beyond the bracket, conferences organise the schedule formula, tiebreaker rules and often the way awards and all-league teams are selected.
They give the regular season a second race, since a team can be far from the best record and still be competing meaningfully for position.
That is the real defence of the structure. It creates two live standings instead of one, and a league with more meaningful late-season matches is more valuable than a strictly fair one.
