Thug rappers abound. Should be no problem getting them to perform for the thug players, and the thug loving fans.
I don't think the issue is that people don't want to perform because they dislike the keenler. On the contrary, I think they don't want to perform because they don't want to be seen as supporting the NFL because racism.
That one guy single handedly created a giant crack in the NFL that is slowly, ever so slowy, splitting the whole thing open.
