Expanding to the West isn’t “necessity” like it is in the NHL because they have EIGHT TEAMS in the Pacific/Mountain time zones NOW, which is fine/good.
(Colorado is the outlier, so they could add ONE Western team if they desired, but I don’t necessarily think that’s smart and they definitely shouldn’t add TWO. Because)
Any realistic format for a 32 team MLB is going to retain NL/AL, and they are going to WANT two groups of four PTZ/MTZ teams, one in each league. (I'm going to including COL/ARZ as "PTZ" the rest of this post)
The thought behind MLB expansion is that they are after:
- Simple, symmetrical scheduling model (They swapped Houston to the AL to ease scheduling making)
- Limited interleague play in “Rivalry weekends” mid-summer they can use to promote the All-Star game and vice versa, and not have one interleague series every day, including April and September (Which they are forced to by a 15/15 split).
With 32 teams, the scheduling model of a 4-4-4-4 in each league is nice and simple:
- 19 division, 8 league, have three interleague series = 162 games
In that scenario, they’d want a four-team NL West and four-team AL West and TEX/HOU wouldn’t want to be with three PTZ teams. They could add an AL team that’s west of Denver (But would you want Portland/Vancouver WITH Seattle or opposite Seattle in the other league like they’ve had in other regions for generations?). Or add an NL West team and move Colorado or Arizona to the AL.
HOWEVER, everyone knows that for the OTHER 24 teams, they’ll never come up with groups of four that make everyone happy. The primary example is with Toronto & Tampa. They each get 18 or 19 at home against New York/Boston. But only one of them would get to be in a four-team division with BOS-NYY-BAL and keep those 19 home games and the other will be reduced to EIGHT.
And it’s like that everywhere, which is why every time someone posts a 4x4 format, there’s a couple replies saying “you shouldn’t separate those two,” or “Team X won’t like that.” And that’s just with us picking our own expansion teams before owners/cities/stadium deals come into play.
So the compromise to avoid that nonsense is two divisions of eight: 12 vs division, 9 vs league, 2 interleague series of 6 games = 162. Therefore, it shouldn’t matter if the AL West is 3 PTZ and 5 CTZ and the NL West is 5 PTZ and 3 CTZ… except that ticks off the other side of the map:
Because now you’re losing 6 or 7 games vs those 3 or 4 current division rivals teams WANT to play because they sell tickets, and adding in 3 more teams. Which in the West Division are in the Central Time Zone. So now people don’t like it because you’d:
- lose 7 BOS/NYY games for TV
- NL West goes from 74 games vs PTZ teams to 48!
- AL West loses a ton of PTZ games
- NL Central teams moving West would go postal, having to play 30 road games in PTZ.
If you have those “two groups of four PTZ teams, one for each league” that means you ALSO have a group of four CTZ teams in the West division of each league. So you can unbalance the division schedule to make everyone happy:
16 vs 3 division teams (PTZ vs PTZ, CTZ vs CTZ)
12 vs 4 division teams (PTZ vs CTZ)
8 vs 4 other division teams
7 vs 4 other division teams
In the West division, the 16/12 distinction can be geographic for game time starts in your time zone.
In the East, the 16/12 distinction can alternate like the 19/18 distinction alternates now.
That way, Tampa Bay and Toronto can each get 28 games a year against New York and Boston instead of someone getting only 8. One year it’s New York 16/Boston 12, the next Boston 16/New York 12. Essentially, the schedule grid would act like TB/TOR switch between “AL East” and “AL North” every season.
Sorry if that sounded condescending. I felt like I sounded really arrogant while writing it. Didn't mean it that way!
