That's what I think too.
However, without Sale the Sox currently have the 2d best ERA in MLB, primarily because of the rotation (Bello, Pivetta, Crawford, Whitlock, Houck, and now Criswell). No one on Talksox can name a Red Sox team in the last 50 years that was ranked higher than 2d in team ERA.
As for Grissom, I didn't expect much from him and am fine with whoever else gets to play in his stead. Next year's middle infielders could include Story, Mayer, Rafaela, Hammond, and/or Gonzalez. Who needs freaking Grissom this year or next year?
I would be dishonest if I didn't admit I would love to have Sale on this Sox team. When he is the real Chris Sale, he is a joy to watch because he's probably the most professional pitcher I can remember in a Sox uniform. Focused, good defender, athletic, and with a pretty good array of pitches, made slightly better by the recent addition of a cut fastball.
