The Brewers have no business extending a high end pitcher at market rates a few years beyond free agency - maybe if Miz is ok with 1-2 years beyond his current UFA year at $35M per with escalating amounts in what would be his arbitration years, but I doubt his agent would advise for that.
We were sad to see Burnes walk, and he promptly blew out his elbow. The Tigers are paying Skubal ~$30M this season to rehab after a minor elbow surgery and miss most of his last year with the team. The Peralta deal was perfect for the Brewers, but i think it wouldn't make sense for Miz at this juncture even if the extension amount was dramatically higher.
Call me a cynic, but I just don't see the point of giving any current MLB talent a longterm extension during this season, knowing there's a darn good chance there may not even be a 2027 season and the financial playing field may be dramatically different whenever the incoming lockout/strike ends. Offering impact prospects long term extensions makes alot more sense to me with the upcoming labor strife - giving them some financial certainty through this storm that could impact the first few years of their pre-arbitration team control (and in turn push their free agent years back longer than normal) seems like the smarter play longterm for the organization.
Truth is that teams can field quality pitching staffs without having to shell out massive veteran contracts - the Brewers have proven that, and I think the injury risk is too high for any impact arm to pay them huge $$$ to spend large chunks of time on the IL.
