He's a complete opposite of his brother. He is a type A personality with the demeanor of a bad sport. I've seen him snubbed fellow coaches at end of games and such. He'll fit perfectly in that setting of a Raiders coach, where the fans are mostly cholos and malcontents. For a reason the Raiders picked Chucky as their coach, he fit well there too but without the winning.
Harbaugh will bring in a ferocious reputation and will make the well named Raiders into a rejuvenated team.
