But it also doesn't really matter if fans "care" where the budget is. It's a cold hard reality. At some point, the team just cannot spend anymore, much lie every business ever. Even Amazon has some sort of spending cap for their expenses. They may be nowhere near it right now, but that doesn't man it does not exist.
The Sox have spent a lot. They are still spending a lot. Casual fan or not, the notion that this team was too cheap to bring back Betts or anyone else is not based in anything realisitic...
