Joe Musgrove just signed an extension with the Padres despite the fact he was set to hit free agency after the season. So, not impossible, but the question is are the Brewers willing to pony up enough to make Corbin even consider forgoing free agency. If he's willing to do a shorter deal than Yelich but with a high AAV, I could see the Brewers getting involved. Any long-term commitment like Yelich, though, and that's almost suicide for this organization.
