They had one of the worst mlb offenses in recent memory last year. They brought in some guys on the margins(Vierling, Maton) and have basically run the rest of the lineup back.
If you want to blame Hinch for the same guys looking terrible through 3 games, that's ok with me. And you can also blame him for not demanding more immediate upgrades.
But this is the roster he was given. It's a substandard offensive roster even if some performance reverts back to career norms.
