Looking further into the father, and all I see is accusations of racism because he didn't want his team to kneel for the anthem during the George Floyd riots, and then got forced to resign from Jacksonville one day after being hired thanks to cancel culture.
That in and of itself isn't indicative of actual racism, despite the accusations, if this all stands from not allowing his team to kneel. That could be due to patriotism.
But I don't know enough -does anyone have anything beyond that? Did he use slurs on the players? Were there any accusations that PRE-DATE the Floyd riots?
