actually that starts in 2023 - every team will play at least one series against every other team.
If they do that, why have leagues and divisions at all? Go to a single table and play a 174-game schedule in which every team plays everyone else six times, three games at home and three on the road (29 x 6 = 174). Of course I recognize part of the point of splitting both leagues into divisions in 1969 was concern that the last-place teams would be so far behind in a single 12-team table that the fans would lose interest, and that would likely be exacerbated in a single 30-team table, but as a practical matter would it really make much of a difference? A bad team is a bad team regardless of whether they're 53.5 games back in a five-team division or 59.5 games back in either the league table or a single table (Detroit in 2019).
(The interesting thing is that a single table doesn't always make a lot of a difference in how far behind the worst team is because several times, the worst overall and best overall teams have come from the same division, which I suppose makes some sense insofar as the best team got to pad their record by beating up on the worst team. 2016 was an exception. The Twins and the Reds both finished 35.5 games back in their respective divisions, but the Twins went 59–103 and the Reds went 68–94. The Twins would have been 36 games back in a single-table AL and the Reds would have remained 35.5 games back in a single-table NL because the Cubs had the best record and are in the same division, but in a single table for the entire major leagues, the Twins would have been 44.5 games back. That's still not hideously worse than 35.5 games back when you get down to it, and either one is a lot better than 2018 when 47–115 Baltimore finished 61 games back regardless of which table you used because Boston had the best overall record.)
