Not really
There are "common sense" reasons for the projections
Vlad, Bo, Kirk, Jansen, Schneider, Varsho, Biggio, Espinal, IKF are mostly presumptive starters and in their 20s. Most of them SHOULD bounce back or be better based on extremely basic principles like their age, how much contact they make, and how hard they hit the baseball.
You can go through the team and point out a couple of geezers here and there, or the age of the pitching staff, but I really don't care when 7/9 presumptive starters are still in their 20s. Common sense says the offense can really only get better vs 2023.
And if you want to think very linear, in terms of players lost and added while ignoring projections, it doesn't even look bad considering it's Jan 18:
Nobody of consequence was lost on the pitching side as Hicks was a hired gun anyway and Ryu was a non-contributor.
CHAPMAN out - replaced his defense at least with IKF and guess what Davis Schneider has a better projected wRC+ than Matt Chapman (not shocking)
KK out - replaced by a genetic replica of KK, you would swear it is the same dude
BELT out - okay but it's January 18th and the FA list is still crowded with DH options
MERRIFIELD out - who really cares? we all watched him the last couple years.
IN --> this Cuban arm and whatever he represents, could be a massive upgrade on the SP5 spot for all we know
The thrust of this is that I don't think you can even find a reasonable argument that the team will be worse than 2023 and there are plenty of reason to think it can and should be just as good or a better.
