You don't cut a guy that you have to pay that much money to whether he plays or not--and who is also the best player at his position. Deal with it. Palmer isn't going anywhere. He's not going to be cut, the organization isn't going to eat that contract, and Pryor isn't going to be elevated to starting qb based on the results of one meaningless game played on the last day of the season. We're also not going to make some blockbuster deal for a FA qb. The biggest splash we'll make at the position might be in the draft. But even then, it's doubtful.
The organization's going to cut everyone they can who they believe is overpaid and/or underperforms. But Palmer won't be one of those players.
