Even if Hoyer has decided to sell, it's to his advantage to pretend otherwise at this point. That may help to get other GMs to come in with the higher offers necessary to "convince" Hoyer to sell out on a potentially-competitive team.
While the Brewers and Reds have obvious issues, Fangraphs odds currently have us at just ~16% to make the playoffs. I'm inclined to think Hoyer has an eye on selling, as we'd need multiple significant upgrades to drastically change those playoff odds -- and that would come in the form of the young guys we need to come through to replace Bellinger/Stroman's production if we want to be competitive next year.
Also, I think Hoyer's comfort spot is being a deadline seller. And with potentially the two best non-Ohtani rentals on the market, selling is going to hold a lot of allure for him. I'm guessing we unload.
