The O's, Rangers, Mariners and Tigers are all horrific. fangraphs projects 65-74 wins for all 4 teams.
The Royals and Guardians are projected under .500.
It's interesting how they project 6 of the 15 AL teams to be under .500 and 10 of the 15 NL teams to be under .500. I doubt that works out that way, but I think we can all agree the Sox are significantly better than those 6 AL teams and 10 NL teams, of which we won't play most of them.
That leaves the Rays (82 projected wins), A's (83), Angels (85), CWS (86) all pretty close to the Sox (88), Astros, Jays & Twins (89). The Yanks are by themselves in the AL at 96 projected wins.
I can't see how anyone can say the teams projected between 82-89 wins, all look better than us, on paper, or at least significantly better where they take 2 our of 3 against us every series.
Sure, if nobody comes back from injury, and all our players who had down years in 2019 or 2020 continue doing poorly, we may come close to 90 wins, but other teams will experience the same things, too.
If you truly believe the 2019 team was as bad as they showed, despite being just slightly different from the record setting 2018 team, then I can see why you see little hope for 2021, but many of those players still on the team from 2018 are still in their primes or not that far past prime to expect something good from most of them. Some were not quite at prime in 2018 or 2019 and could be expected to do better in 2021.
Our 2021 health is nearly impossible to project, so much depends on how you feel players like Sale, Eovaldi, Richards and ERod will do, and how many innings they give us.
