These teams have been waging war for decades, dating back to their bitter dispute in the old days of the AFL.
Boss sounds like a man happy to shed the garb of the Silver and Black.
"I was in Oakland for such a short period of time that it wasn't really something where I really understood the whole Chiefs-Raiders rivalry," Boss told KCSP-AM in Kansas City, via SportsRadioInterviews.com. "I just know now that I'm on the better side of the rivalry. ... It's been a great transition and it's really been a blessing in disguise to have been moved on to greener pastures."
For a man who doesn't claim to understand the nature of this rivalry, Boss exhibits a preternatural knack for irritating the citizens of Oakland. This is promising.
