https://www.espn.com/mlb/story/_/id/...odgers-yankees says that with full health, the Yankees, Astros, and Dodgers are much better than the best combined team from the Orioles, Royals, Tigers, and Marlins. Each team was given a roster of four starters with 165 IP (because you only need four starters in the playoffs), seven relievers with 65 IP, one swingman with 95 IP, eight hitters other than the catcher with 600 PA (giving the Dodgers a DH), a catcher with 500 PA, and four bench players with 250 PA. That adds up to 6,300 PA, which is 38.89 (38 8/9) per game. Considering the Yankees have an elite offense and are averaging 38.54 PA per game, 6,300 is too high. Considering author Sam Miller gave the starting catcher 100 fewer PA, he should have given the sub catcher 275 PA and the other three bench players 225 PA to be 6,250 PA, which is 62.58 per game. Players like Severino and Betances who have missed the whole season were ineligible, but Stanton was included. Players who are out for the season or who went from one of the bottom teams to another team were excluded. The Yankees roster was:

Sanchez C
Voit 1B
LeMahieu 2B
Urshela 3B
Torres SS
Stanton LF
Gardner CF
Judge RF
Encarnacion DH
Bench: Romine
Bench: Gregorius
Bench: Maybin (meaning that Hicks, Tauchman, and Frazier aren't on this roster)
Bench: Ford
Paxton
Tanaka
German
Happ
Swing: Loaisiga
Chapman
Kahnle
Ottavino
Green
Hale
Britton
Cessa

Using WAR, the Yankees roster would get 110 wins with full health for the players above. The fact that they are on pace for 106 wins shows how well the "next man up" guys have done. WAR has the Astros at 74.0, Dodgers at 69.9, Yankees at 62.2, and Superteam at 50.3. Including the fifth worst team, Toronto, improves the Superteam to 58.1. Toronto would have one-fifth of those 25 players, which is its share if the bottom five teams were equal, which is surprising considering Toronto is the best of the five. Adding Seattle as the sixth worst team improves the Superteam to 64.3 to pass the Yankees. Each team's share would be 25/6 = 4 1/6, so it's surprising that Seattle would only provide four players. The seventh worst team is Colorado, and they would provide six players. The Superteam WAR would improve to 68.4 and still be worse than the Astros and Dodgers. The eighth worst team is Colorado, and they would provide four players. The Superteam WAR would improve to 72.9 to pass the Dodgers and trail the Astros. The ninth worst team is the White Sox, and they would provide four players. The Superteam WAR would improve to 75.7 and pass the Astros. As the next worst teams add players, players are removed. For example, Toronto had five players when they were first included, but had fewer players when the Superteam had players from nine teams. Here are the rosters of the Superteam from the worst nine teams and the Astros:
