There’s always complaining about the Red Sox. Whether they are 69-93, 93-69 (two years in a row!), or on pace for a 110 win season, it’s World Series or bust.
In their defense, a lot of the disappointment comes from two straight ALDS exits to the Indians and Astros. It’s worth noting that both of those teams played in Game 7 of the World Series in their respective years, with one of them actually winning it all. So the Red Sox were beat by the best, and there’s no shame in that.
