Here's the real problem with this, the Joneses shot their mouths off and put themselves in a corner when they could have let him play out his contract and made a decision after next season. Just as the Skins played it with Cousins and then tagged him twice.
Is there a real market for Prescott outside of the Cowboys? Do they think they're going to get into a bidding war with other teams by letting him play it out? Almost every team has had the opportunity to game plan against Prescott, they know better about his value as a QB1.
One thing that seems to be prevalent on this forum is the belief this is a coaching problem, not a QB problem. Change the OC and QBC and voila, Tier 1 QB. Since when did the OC throw any passes or worse, miss open receivers?
How many of the 31 other teams consider Prescott a true QB1 that can improve his accuracy? Or is he viewed as a backup QB by most of the other teams? Would any team, other than the Cowboys, bring him in as QB1 or would they make him fight for it?
The major problem I see in all of this is the evaluation process. Any QB should be evaluated with his weapons out of the mix. Does he elevate talent or need it to elevate himself? Is he dependent on that talent? What happens when that talent is not available?
What does Prescott look like without Elliott? What did he look like before the Cooper acquisition? Pay him based on what he looks like without them. Don't overestimate what may not be the most important piece of the puzzle.
