NFL - Antonio Brown Threatens to 'Quit'

Since joining the Raiders, Brown has frustrated his new bosses by showing up late to numerous meetings and by often appearing unfocused in them. Brown, according to witnesses, typically glances at the screens of several tablets and his smart phone during meetings, distracting himself by engaging in activities which include perusing his bank accounts and "liking" photos on Instagram.

Daniel Kaplan of TheAthletic.com reports that Brown’s case included a warning that “if [Brown] suffered a head injury in a helmet that he is compelled to wear, he would hold the league liable.”

The source also provided this quote to Kaplan: “I think it’ll be interesting if the NFL forces Antonio to wear a different helmet. And he does play and he doesn’t retire as some people have reported he will do. And then he suffers a really severe injury. I’d hate to be the NFL. Because now you’ve forced him into wearing a different type of helmet. And I think at that point, though, the liability will be dramatic.”
