You trade guys you don’t want next year, or have contracts that should be gone in a year or two - all dependent on value.
Minkah probably has value. Chubb has a few sacks and a contract that should be gone. Phillips is on a fifth year option - won’t get much.
How many years does Brewer have on his contract? He may have value, but I would rather have a competent center.
I would not sell for the sake of selling. Say Patrick Paul. We hit on a LT in the second round. Why even take a first for him, when it would get spent on another LT?
I would say something similar about Waddle.
But I have to admit, there aren’t many “you better pay up” players on the roster. I could add Achane, but he’s close to his second contract and a RB.
