I know this thread is intended for 2019 only, but the future budget choices, especially if a reset is in the plans after 2019 or 2020, affect the choices we make now.
Here's one view of the situation, if we choose to reset after 2019:
Start by subtracting Porcello, JD (opts out), Bogaerts, Sale, Moreland, Pearce, Nunez, Holt & Thornburg (some may be added back, if we stay under). That leaves this as the 2020 base to work from:
Luxury Dollars in millions
31 Price
~26 Betts (last of 3 arbs)
17 Eovaldi
13.8 Pedroia
~13 JBJ (last of 4 arbs)
~9 ERod (3 of 4 arbs)
~6 Barnes (2 of 3)
~5 Wright (3 of 3)
4.5 Vazquez
~4.2 Beni (1st of 3)
~3.5 Leon (4 of 4)
~3.5 Hembree (2 of 3)
~2 Workman 3 of 3)
~1.5 Swihart (2 of 4)
$141M for 14 players
$15M benefits
$8M 11 players at min MLB wage
$3M 15 players on 40 man roster in minors
$167M TOTAL
$208M Tax threshold for 2020
That leaves $40M to spend and stay under to reset. We could bring some of our players back but certainly not close to everyone. We could sign a bunch of low to mid range free agents and look to try and contend to a small extent, or look to go large right away in 2021 by keeping Betts, JBJ and others.
Here is a rough estimate on what our departing players might get in 2020 (per year)
$30M Sale
$24M JD
$24M Bogey
$18M Porcello
$4M Nunez, Moreland, Pearce, Holt
We may be able to keep JD or Bogey and Porcello or a pitcher at $14-16M or so, but there would be nothing left over for the rest of the roster. We'd have 8-9 guys at min wage on the 25 man roster. It's hard to contend when you have 9 replacement level players.
