Looking at B-R.com's positional rankings:

The Brewers were 6th in wins above average at 1B. Plenty of teams can upgrade there.
And, for as bad as Yelich was, the Brewers were 22nd at DH. Padres, Angels, Blue Jays, and Mets were worse. Quite a few teams can improve on DH if they already have a 1B. And he can play OF in a pinch.
Bauers had a .863 OPS vs RHP this past season, and a .901 OPS vs LHP. It's really hard to find that balance; part of his value is that you don't have to platoon or PH for him.
I think 3/$50M is a good number, maybe up to 3/$60M because of his ability to play multiple positions and not need to platoon or PH.
