The OP brings up a good question for discussion. Yeah, we all like Dez and hope he stays a Cowboy for life under a fair contract and stays out of trouble. Well, life don't always work that way and you need to have backup plans. I am sure the Cowboys and the Broncos have contingency plans for Dez and Demaryius in scenario a) player demands get insanely ridiculous or b) a team offers a ridiculous contract and is willing to give up 2 #1s undr the franchise rules. Scenario A would necessitate a trade and try to make the best of the situation. Scenario B would be the same as trading Dez for two #1s.
I am still a little worried a team like Oakland, Jax, or Clev with a lot of cap money needing to be spent will offer Dez or Demaryius a $16-18M/yr contract and be willing to give up two #1s. Some later drafting team would also be a concern if they had a lot of free cap space.
Like Bellicek said, everyone, including myself and Brady, are available for a trade. Depends on what you are offering. Seattle won the SB without a star WR. NE won the SB without a star WR. Face it, we all have a little concern (rightly or wrongly) that Dez will do something crazy. If you heard on the news that a Cowboy was arrested, you come right here and hope it wasn't Dez (or Hardy too now).
You are talking about a huge contract with a lot of guaranteed money. That is a lot of eggs in one position. An injury or something else with that player would have major ramifications for several years just like Romo. How many of us ran right to overthecap after Romo got hurt in the Washington game? So, you have to weigh the players potential risk and reward.
If Dez wants Suh-like money (if I were his agent, I'd say Dez is worth more than Suh). Jerry, would you trade Dez for Suh straight up? I wouldn't. So, Jerry...pay him accordingly? If I'm Jerry, I ain't paying that if that is what he is demanding or some other team is willing to pay. And you move on.
I have no idea how much Dez is asking for? I have no idea what other teams are willing to pay him. Jerry does, though. You compare what he is asking, what can he get realistically on the market, and what is available in his place. Weigh your options.
If some team before this year's draft is offering Dez $16-18M/yr with $50M guaranteed, I am not matching. Give me the 2 #1s. Too much risk for me. I like him as a player but I just can't feel confident doing that type of contract.
