I've seen this before working in sales. The money isn't a big a it is in the NFL, but the egos are comparable. We had a couple of guys over the years that were really good at their jobs. They brought in big money, and because of that they were given a pass. They got it in their heads that they could do the same anywhere, and their attitudes became a detriment to overall production.
They stuck around for awhile, but then they started openly questioning and criticizing the GM. There was the eventual war of words, yelling matches, and just like that, they were gone.
Dak isn't bigger than the Dallas Cowboys. I've criticized the Jones family as much as anyone over the years, and would love nothing more than for him to have his ego checked...but not at the cost of the chemistry of the young core we have in place. The Jones family has been very generous towards Dak and have made him an incredibly wealthy man. The least he can do is reciprocate that by showing some humility throughout this process, whether it looks like he's sticking around, or not.
