I don't think the 2021 Braves were "garbage" and "one of the worst teams ever" to win the World Series. They weren't the favorites or best team heading into the 2021 Postseason sure but they had the right mix of talent and luck regarding some players they brought in at the trade deadline. Things clicked for them at the right time.
- Rosario hit .383/.456/.617 in the 2021 postseason. Had some solid years with the Twins before, nothing special. Posted a 4.0 WAR season in 2018.
- Soler hit .242/.342/.606 in the 2021 postseason. 48 HR's in 2019.
- Duvall sucks I know, though he still hit 38 HR's in 2021 and posted a 2.7 WAR.
- Pederson didn't do much with the Braves, though had some big hits in the Postseason. I recall a lot of posters on this message board wanted the Jays to acquire Pederson at this past trade deadline.
- Matzek was decent in 2021 (2.57 ERA, 3.20 FIP, 11 K/9 and 1.1 WAR). In the postseason he had a 1.72 ERA, 0.87 FIP and 13.79 K/9 in 15.2 innings. Better lefty than Tim Mayza! Will Smith wasn't that good, will admit. Braves had a far superior bullpen during the 2022 regular season and heading into the 2022 Postseason.
The Braves in 2021 weren't that bad of a team, even without Acuna. AA did a great job acquiring some bats with previous success at the trade deadline to fill in for the injuries they had. Sure those turds got lucky and were productive, though they also had previous success at the MLB level before. Freeman, Riley, Albies, and Swanson were still solid. Yes, Riley and Swanson were better in 2022, though they still were solid in 2021 and progressed even more as you would expect with young players with their skillsets. Albies put up 3.9 WAR in 2021 while Acuna wasn't even at his best in 2022 posting a 2.0 WAR.
Obviously, the 2022 Braves team is far better than the 2021 Braves team was on paper. Though I don't think the 2021 Braves were "garbage" at all. They had some solid young pieces who broke out, Freddie Freeman, some solid young pitching to go along with Morton, and got lucky on some trade deadline acquisitions that did an adequate job replacing Acuna and Ozuna.
