They might not lose as many, but they will have a season similar to the 23 Sox. They got over 15 fWAR from Julio, Suerez and Big Dumper last year. That won't happen again. Not to mention they got like 7 fWAR combined from the catcher spot. They will be lucky to get 3 this year.
Julio is a nice player and he's probably more exciting than Luis, but I think Luis is better. He has more raw power for sure.
