If money was no concern at all I say sure, sign him. Bring everybody back etc. But there is at least some budget in play when you account for the luxury tax. They have gone over it but I think overall they want to bring that number down especially with some younger players coming up for big deals like Betts and Bogaerts. I know they have all the money in the world, just thinking like they are thinking. They want to bring the number down if at all possible. So that means saying goodbye to a guy like Kelly and probably Kimbrel too. They prioritized Eovaldi which I have no problem with. Really, if at some point you want to turn to Eovaldi as the closer or 8th inning guy I could see that working out.
Money is part of it, but realistically they can't re-sign all of their core guys. Betts is the important one, and he's UFA after 2020 season.
Sox have Sandoval and Castillo dead money all off the books by then, which is around 34 million, AKA Betts' money.
Bogearts is probably a walk. Boras guy, will look to reset market. Not sure I'd pay him what he'll get.
JBJ is a walk or trade. Doens't bring enough to warrant a big contract.
Benny has until 2023 before UFA, not a priority in next few years.
JD Martinez is an interesting case, as he can opt out any year after this upcoming season.
Sale is also UFA after 2019.
No reason to not go for it again in 2019. They're already over the tax.
