Strictly IMO's from observation:
If you like long slow 100 pitch games in the 5th inning, Martin Perez could be your starter. Not much there
How long can Chavis continue with a 50% K rate ?
Mazza is not the answer to any question which addresses the depth of pitching talent on this team
On a positive note the Red Sox will continue to score runs with a lineup of Beni, Devers, JDM, Bogaerts, Vazquez, Moreland, JBJ on one of his streaks. On Erod and Nate days, they will be winners more often than not.
Dalbec looks like a 1Bman, Chavis doesn't. Other than Brock Holt, who else besides Chavis is considered your platoon 1man, and your sometimes 2Bman. Not a likely combo of talents.
