Crunching the numbers:
1) Gonzalez already DFAed, we eat 21.5M or almost 3 WAR at market rate
2) Kazmir at 16M. Probably finished. We eat 2 WAR at market rate
3) Brandon McCarthy. Expect him to be a 2 win pitcher in 2018 and 1 win pitcher in 2019. Expected surplus value about 1 WAR.
4) Culberson. Replacement level player.
So cumulatively these four have an expected negative surplus value of negative 4 WAR.
Kemp has an expected negative surplus value of negative 4 WAR.
So I would say its a wash. Any exchange where we get some cash makes it a win.
Additional thought, we basically moved deadweight money out 2019 into 2018. So this may move up our expected opening of our competitive window from 2020 to 2019. From the Dodgers perspective, it makes it easier to get below the luxury tax threshold this year (not sure if this is a priority of theirs).
Additional additional thought. I like the McCarty pickup and think it gives us a solid rotation for 2018.
This looks like a very good first big trade by AA. Maybe a great trade depending upon the cash changing hands.
