I'm not here to debate whether or not he deserves the $, I think he should be paid very well, but I also think QB's need to wise up if they want to win rings. Teams can't afford to pay them such large portions of their budgets and still contend for very long.
Considering the igglets over paid Carson and did it a year earlier than necessary, indicates to me that they did so deliberately to hamper our negotiations with Dak. They know we were trying to get a fair, but team friendly deal done so that we could continue to sign good FA's and push for a ring. If Dak gets that kind of $, most of that stops and we will lose some of our good players as well.
It's somebody's else's fault.
The Eagles have been identifying young players they want to keep and signing them a year early ever since Banner was in the FO. Players will usually take a below market deal early to shift the injury risk from the player to the team. And for a boatload of guaranteed money. They didn't do anything to spite the Cowboys. What's next? The Falcons extend Julio Jones and the Saints sign Michael Thomas before the Cowboys sign Amari Cooper out of spite to make negotiations harder between Cooper and the Cowboys?
SJ and JJ have known they want Dak to be their franchise QB, at least since last season. With Dak's agent's cooperation, they could've been setting everything up over the course of 9-12 months leading up to the new league year of 2019. They couldn't have signed it and made it official until the new league year this season. But there's no rule against talking about it.
It wouldn't surprise me if Jerry Jones is purposely waiting until the talk of OTAs (predictions on final 53 rosters, winners and losers of OTAs, etc) dies down and media is searching for anything to talk about to sign Dak. He's a master marketer. And what better way to get all the media talking about the Cowboys than signing Dak during the lull between the end of OTAs and the start of TC?
