That may be true, but that doesn't mean he doesn't want to be in Dallas, so lets at least be fair minded in our conclusions.
And, of course, the Cowboys have to set their priorities as well, and some have suggested the fact a deal didn't get done means they don't want Dak, which makes no sense because if that were the case they wouldn't have insisted on a 5 year deal.
It's just the business side of things on both sides, and how things stand doesn't mean either side doesn't prefer to stay connected with the other.
By the way, I've never seen anything suggesting Dak was asking for a 3 year deal. Seems a lot of people throw things like that out to bolster their argument, along with the idea Dak was asking for an average of $40 million/year, even though the reporting has not been in line with those ideas. Most reporting has been he was looking for 4 years at around $34-35 million per year, with $100-110 million guaranteed.
