The league doesn't see it that way.
That's because the league doesn't fit a strict authoritarian structure like an NFL team. It's Goodell and the 32 owners. But if Goodell disrespect the league's owners or tells him to kiss where the sun don't shine, Goodell would be Gonedell.
Second, the league's job is to establish and enforce
policy. Insubordination is something a team would deal with, not the league necessarily.
Lawrence, Gregory, and McClain will all miss a considerable portion of the upcoming season. Hardy is available to play in all 16 games.
He's available if someone wants him. Apparently, no one does.
And, again, I only wish I could see or read credible proof of any of the rumored "insubordination", and "disrespect to authority" and "rebellion" that's commonly cited as a valid reason for Hardy not being back. If I had credible proof of what it was, it would help me to personally judge whether it warranted NFL exile for the player and a huge weakness for the team.
I can understand you wanting to see evidence. Unfortunately, we really don't get much evidence of many issues involving players and teams.
However, for me, I can't see why the Cowboys wouldn't want to re-sign Hardy to a friendly deal, especially since they've already taken the PR hit for the initial signing Hardy. I think he's not with the Cowboys for two reasons:
1. He was insubordinate, and I say this because of rumors about his conduct and behavior both with the Cowboys and the Panthers and
2. He wouldn't remain silent about his domestic abuse situation, instead adding more fuel to the fire with his interview with Shefty.
I think the combination of the two resulted in the Cowboys saying, "See ya!" However, I honestly believe had Hardy been the model citizen with the Cowboys, he would still be with the team, regardless of the leaked pictures of Holder and her bruises.
