The Red Sox, until Dombrowski came along.
Seriously though, I 100% believe it should be possible. I have said many times that since the Henry era began, I have felt that, going into the season, the Sox were legitimate contenders every year. That doesn't mean that it always works out on the field, but I have not started any season thinking that the Sox were not a contender.
If 2020 were a regular 162 game season, this might be that year.
