Actually, I think the NFL went south long, long ago. The kneeling is just the final nail in the coffin.
The NFL lost all my respect when they became apologists for thug players who raped, abused women, took drugs, assaulted people, murdered, and basically lived outside the law with rarely more than a slap on the wrist. The owners (and the police and politicians who worshipped sports) didn’t care as long as they were winning games and - more importantly - bringing in money. Most of the fans didn’t seem to care, either. But the kneeling business finally hit a nerve.
I used to watch some pro football because it was a good excuse to drink on Sundays and Monday night, but I don't really do that anymore.
