Here is my suggestion to strike a balance between the situation pre-1994 (where teams winning more than 100 games would sometimes miss the playoffs) and the situation today (where 10 of 30 teams make the playoffs, including ones with worse than a .540 winning percentage).
I know that this will never happen, because the economics of the game dictate that more teams in contention means more fans at the stadium and better TV ratings. But if it were fair, this is how I think it should be:
- Eliminate 2nd wildcard
- Take the best non-division-winner. If they lost 70 or fewer games, grant them the wildcard, and put them in a 7-game (not 5) series with the best division winner. The other two division winners will also face off in a best of 7. If every non-division winner has more than 70 losses, give the best division winner a "bye" in the first round.
- Eliminate the All Star Game determining World Series home field advantage BS. Award it to the team with the best regular season record.
This would accomplish the following:
1) Make sure every team in the playoffs either won their division or lost no more than 70 games.
2) Eliminates the ridiculous 1-game-playoff series (except as a regular season tiebreaker)
3) Restores home field advantage in the World Series to the best regular season team
4) Gives a substantial reward to the best regular season team in each league, to where they will sometimes skip the first round if there is no wildcard team.
