You sound kind of "half-empty" there Pack. Guess it depends on what you consider long-term. This team has had plenty of valleys in their history and the folks keep coming to the ballpark. They drew 2.5mil last year despite essentially being in the cellar all season. They drew better than Pittsburgh, Houston, Arizona and Minnesota, teams that were in the hunt pretty much all season.
Sure the people at the top may change, but unless there is something in the air, I don't see why Attanasio will sell. He loves baseball, there aren't good teams for sale every year so it's not like he can just choose to buy a better team, the city and fans have been pretty supportive, etc. Not sure why he would walk away before seeing the current "valley" through to to some logical endpoint. Makes no business sense to sell when the price is low.
Yes, Counsell might be gone just because managers tend to wear out their welcome after 4-5 years, but I suspect Stearns will be here at least 5 years given how much Attanasio has invested in letting him gut the team and rebuild. You don't "invest" as much as they are and then bail after a few down years. The only way I see Stearns leaving before 5 years is if someone else raids the Brewers but I suspect that will be tough to do unless you offer him a position more than just GM.
