The owners don't care about player safety and they're ostriches when it comes to understanding the real long-term threat to viewership that the league is facing.
The union is too dumb to cobble together a coherent approach to player discipline and safety.
And frankly, society as a whole in 2017 has completely lost its moral underpinnings. The Boston announcers cheered Gronk's actions in realtime. That doesn't seem the least bit out of place with what has been going on everywhere. People have been so lied to, and so broke, for so many years, that they've basically thrown ethics and decency out the window. Nothing surprises me anymore.
