If you non-tender Renfroe then you would probably just want to run with an all rookie OF. All of the OF in FA that are close to Renfroe's skill level will all cost more than the estimated $10m that Renfroe would be getting. The only way you are going to be able to get someone cheaper is to get someone on a bounce back type of a contract. You would have to roll the dice and hope Gallo returns to his former self and can cut down on the strikeouts.
Joc Pederson hasn't really been all that much better than Renfroe and career wise they are about equal. I think Pederson is going to get a big pay bump after the year he has had offensively. He should get a 2-4 year contract that should give him an annual salary around $13-17m. Something like 3-years $50m sounds about right for Pederson.
I don't see the Brewers paying FA$ on an OF. If they are going to spend money in the OF it will be to keep Renfroe for another year. I don't see the Brewers going after an OF this off season in FA. Maybe they would do Brantley or Haniger but that would be to play them at DH and not in the OF.
Here are the possible OF Free Agents and I don't really see any that I would want to pay more than $10m for besides Judge and that is just LOL no chance for the Brewers.

I would really like to see the Brewers trade one of Woodruff or Burnes. I have mentioned before an Orioles trade for Rodriguez/Holliday plus other spare parts. I think the plan should be to retool for 2023 trading away either Burnes or Woodruff and then trying to resign one. I think Woodruff is the more likely resigning as I think that would be in the Brewers price range. I wouldn't be against trading Adames if the right trade comes along but looking at the possible FA SS's this doesn't look like a good year to trade a SS or to be a FA SS. There just are not that many teams that will be looking for a SS. Of the possible contending teams maybe the Cardinals but Arenado's extension may price them out of the FA SS market and I think the Cardinals may look at SP more this offseason than a SS.
