The only reason to keep the core group (aside from wanting to sell tickets in hopes that the team contends) is if you believe a new hitting coach/philosophy/preparation can make the existing talent better. Maybe that could work, maybe it won't. It's a risk with only a year of control left on Vlad/Bo. Honestly, that Mattingly quote about "damage is a scary word" has been brought up before, but the followup to that was even scarier:
“I don’t really see us as a huge power club. But we do have a chance for, I think, four or five guys hitting 20 or above. That would be good for us.”
They literally have a 25 year old with an elite statcast page that hit 80 home runs in 2021-22, but as soon as Donnie came on board, now he maybe, possibly, if he's lucky, could get to 20 or above. Even though he drills everything into the ground at an even higher rate than before, and his ability to hit a 4SFB suddenly disappeared out of thin air. Something isn't right. So between that and Bo having a down year, you could certainly argue that bringing them back for one more try with a new coaching staff would be more logical than having Atkins trade them for 42 years of control on the most mid prospects imaginable.
