Let's factor in here that it's completely possible if not likely that Rosenthal has slightly mischaracterized what the Brewers are doing with Hader. I doubt we're calling teams like "hey Hader is available, what's your best offer". What's more likely is in talks with other teams, Hader has come up in discussion and certain other teams with big mouths made comments to Rosenthal. I wouldn't be surprised if Yelich, Woodruff, Hiura, Knebel, etc...literally everybody on the Brewers that has value has probably come up in discussion at some point over the last year and a half or so. Stearns has quite the track record on trades, to the point that it's very unlikely he makes a glaringly bad trade when moving Hader.
