A couple weeks ago I thought the Brewers would surely decline Wong's option. Now I'm not so sure, and it all depends on what they can do with Jace Peterson. If they bring him back, Wong should be gone. Urias becomes the super-utility (3b probably the most), and Turang plays several positions, but mostly 2B. Brosseau does Brosseau things.
If they don't bring Peterson back, Wong could come back. Urias becomes an almost full-time 3B, Turang becomes the super-utility, and Brosseau continues to do Brosseau things.
I'd rather have 2 years of Jace for $8M total, rather than one year of Wong for $8M.
Then there's the option of acquiring (trade, FA) a full time 3B; in that case, Wong is gone. There aren't many opportunities to acquire a better 3B than Jace without paying a lot (Like $36M a year for Arenado).
