I don't think it's a given Myers is gone. It's hard to find a competent center that has a good relationship with the QB. While Myers has his warts, I think he's a lot better than his X4 critics give him credit for.
Jaire I am less certain of...if nothing else, he's a raving loon. If they can find a willing buyer that will come close to their reasonable valuation for him, they will deal him...but again, finding a quality starting CB1 is very hard to do. I don't see them getting a straight up #1 pick for him either...best case it's maybe a 2nd or 3rd that can escalate to a #1 if certain metrics are met.
