The Brewers didn't want Adames. They offered the QO to get the draft pick, not to keep him. They wanted no part of his aging years. Given that the Brewers gave up on him, you still gonna be there tonight and boo him?
Offering him one year can be viewed as an insult, at least non-competitive, and obviously way below market value. If my company offered me well-below market value to stay, I would see the writing on the wall and leave as well. I would go where I was wanted.
