I'm assuming Kimbrel will be resigned and his contract next year will be at least at the same AAV of Chapman, unless his production suffers big time during 2018 (I don't see it happening), it will be a very interesting decision for you guys, because he will try to get at least 5 yrs.
Pomeranz will be more expensive too, if he has a similar year in 2018, AAV close to 20 Millions.
In top all of that you young players will get more expensive like Betts, JBJ, Bogaerts, and otherts, a tough decision might be coming next winter with Kimbrel and some other guys
