Sherman has bravado, he made bring a brashness to the field, however, we are all guilty of moments where we should of acted better. Look at Cosby, he’s been preaching that black people should stop acting like the white people are their only problem, yet now he’s been discredited as a rapist, does that mean he’s incorrect about how black people should view themselves? Sherman hasn’t been accused of anything like Cosby but I guarantee his message will get lost because of his personality and that’s very very sad.
Certainly possible, but perhaps it's a "Nixon in China" thing. Only a rabid anti-Communist could get away with negotiating with the Chinese, and perhaps only an outspoken black man with dreadlocks can make an impression on those who wouldn't listen to Peyton Manning.
