Well, decisions have to be made before 2020 (and before) as well, and with rising arb costs, replacing departing players will not leave much room for FAs or massive extension costs.
I think we'll be okay after 2017: $29M
$13.5M Buch (replace with Owens/Johnson)
$7.5M Young (replace with Swihart)
$5.5M Moreland (replace with Travis)
$2.5M Abad (replace with Scott)
Arb raises to some of these players could be very costly
3 of 3 Pom, Kelly & Ross
2 of 3 Bogey, Thornburg, Holt & Rutledge
2 of 4 JBJ & Leon
1st arb Betts, Smith, ERod, Wright, Swihart & Vaz
We might have a little left over for a FA to fill a role.
after 2018 (2019): We may lose Kimbrel, Pom, Kelly & Ross
--not much money coming off the books, but we still have 5 SP'ers on the books, so maybe we can get by with in-house solutions, except for maybe a closer (Thornburg/Smith?).
--Again, even bigger arb raises is going to way outpace what we save by letting Kimbrel, Pom, Kelly and Ross go.
--Who will back fill the pen with no money to spend? If we decide to keep Kimbrel, like I said in my scenario below, then we're way over the luxury limit again.
--We could start seeing serious issues as early as 2019, but I still see us as serious or highly competitive, even if we lose Kimbrel, Pom, Kelly $ Ross.
After 2019: Huge decision time. Rebuild? Pay a huge tax? Keeps some-let others go?
--Pablo off the books will help a lot, even with a $5M buyout (paid in luxury tax dollars prior to 2020). HanRam will hurt, but Devers should be helpful. Porcello & Bogey are going to be the key re-signs.
--Huge arb raises
--we could see some major roster changes for 2020, but I still think we could be major contenders. Lots of "what ifs".
