Here's what MLB once the Rays are sold and a stadium deal is done:
#1 - Start expansion bidding process.
#2 - realign into four leagues:
AL - MIN, CWS, DET, CLE, TOR, BOS, NYY, BAL
NL - MIL, CHC, STL, CIN, PIT, NYM, PHI, (WAS or MON)
Pacific - COL, ARZ, SD, LAA, LAD, LV, SFG, SEA
Southern - HOU, TEX, KC, MIA, TB, ATL, CAR, (WAS or NASH)
Play 16 vs your league (112 games), play 4 games vs 12 interleague teams, rotating over 4 years to see everyone (48 games).
Playoffs: 2 vs 3, winner gets 1; semifinals and World Series.
The reasons are
A. TV times. The West gets like 17 more road games at 7 pm local instead of 4 or 5 pm local when their fans are at work. That's money. The eastern teams play EIGHT games out west (10pm) instead of 24-28 games). ALL Central teams are tied to the East.
B. History/tradition. Cincinnati has been NL for 149 years. The teams leaving the AL/NL are teams with 30-70 years.
C. Travel. All 4-game series is 40 series instead of 54. That's 30 flights instead of 45.
D. Competitive balance and financial equality. The gap between richest/poorest divisions shrink drastically.
And most importantly, the votes. Teams moving divisions have full veto rights. The 16 teams in the AL/NL wouldn't be able to veto, only "vote no" (an 18-team super majority needed to pass).
In the realignment fight, teams like CIN, PIT (poor) are going to say "No, we don't want to be in the division with Mets/Phillies (Rich)." Well, instead of CIN being able to blow up the whole thing, they need 12 other teams saying no to blow up the whole thing.
The teams with veto power are the biggest winners: the West, HOU/TEX (27 more games in ETZ/CTZ). Miami, Tampa, ATL get out of rich divisions HOU/TEX who are a level down in spending instead.
Expansion teams won't have veto power.
But finalize the realignment plan BEFORE finalizing expansion. If only 6 teams will go south, then you take 2 southern teams. If Colorado won't go West, you can add Salt Lake or Portland and push WAS south. OR you can change the name of "South" to "Continental" and it's just all the willing volunteers to be together.
