Dude was blackballed from the league. Just straight-up infringement of the first amendment when the president is saying don't hire the dude due to his freedom of expression.
The pig socks were a huge misstep, I don't actually think Kap is the brightest guy or the best leader for this movement- but I think his basic point is just and he lost his well-deserved job over it. Since then he's put his money where his mouth is helping black communities, but he wore pig socks once. GET HIM!
All that said, it's been 3 years, he thrives in a particular kind of offense, and yes, there'd be a media circus. I understand not wanting him now, but I also feel like someone like the Dolphins should take one for the team just to bury this issue. Either he has it or doesn't and if he has it the attention shifts to football, if he doesn't he can be released for the right reasons this time.
