I think it's a pretty safe bet he gets to 12 WAR over the next 5 seasons. He posted a 12.5 fWAR (10.4 bWAR) over the last 3 seasons. A couple more average seasons like the last 3 and not a huge fall off after would get it done easily. (I wanted an 8 year $144 M extension for Adames 2 years ago) His contract is going to be 6-7 years on the FA market not 5. If the Brewers are giving out a $100+ M contract this offseason, I'd prefer it go to Contreras instead of Adames because you can get a sub $20 M per year for the FA years with Contreras compared to the $25+ M per year an Adames deal would cost. 10 year $155 M for Contreras would be what I would target. (6, 10, 15, 17, 17, 17, 17, 17, 17, 17, and 5 buyout on 17)
