It's only been 3 seasons without the one game play-in. In 2 of those 3 years, the "best team" in one of the tow leagues won. (LAD in '24 and HOU in '22) Texas looked like a crapshoot win, as only 1 other playoff teams had as many or less wins.
From 2012 to 2021, when they had the one game play-in and then the same 7 total series in the format, we saw a "best team" win in 5 of the 10 seasons. That is far from a complete crapshoot. in 2 other years, the second best team from a league won (SFG in '12 and HOU in '17 had one less win than CLE) That's 7 in 10 years the 1 or 2 team won out of 5 teams from each league in the "shoot." Only twice did the worst playoff team win the WS, which is in line with "crapshoot odds," since a total crapshoot would predict 1 in 5 or 2 in 10 wins.
The 3rd and 4th best teams have had way less than their "fairshare" of WS wins. (The Nats in 2019 being the only one.)
