Looking to 2018, the sox cap space is limited.
In terms of long term contracts, you're at $132 mil (Pablo, Hanley, Sale, Pedroia, Price, Porcello, Kimbrel)
You'll have to go through arb again with Bogaerts, Bradley, Holt, Kelly, Thornburg, and Pomeranz. You'll have to go through it for the first time with Betts. Arb really looks at the prior two seasons, so even with Bogey struggling, his 2016 will weigh heavily. You're likely looking at $35 mil for those 6 guys.
If the cap is $195 and DD doesn't want to cross it, then you've got $32 mil to fill 12 spots on your roster. Otherwise known as no big deals to be made this offseason
