I kind of agree that it's hard to pin down what this team will be.
At best, this starting rotation could be dominant and the Sox offense is just good enough (Devers, Casas, Duran, Campbell, Anthony) to slide them towards 90 wins and an easy playoff birth.
At worst, injuries and bad defense hampers the pitching while the offense suffers through a mediocre year as the Sox fall below .500 again.
