Fans should always remember- no NFL player- especially a starter- has an agent who will say, “Let’s agree to a team friendly deal”. Not going to happen. And honestly shouldn’t happen. These guys are gladiators who should try to make as much as they can, while they can. Market value is fair.
In short, Biadaz will expect market value in his second contract and nothing less.
The real question is, should the Cowboys pay that? I may change my opinion at some point but as of now, I wouldn’t pay him because I think you can find another C in the draft or FA.
With contracts for Diggs, Parsons and Lamb looming on the near horizon, Biadaz‘s deal would have to be considered way less important.
