It's RAIDER WEEK!
That doesn't seem to mean the same thing these days as it does back in the day with Marty Schottenheimer, who really fanned the flames of this rivalry. Former Chief Neil Smith joined Danny Parkins and Carrington Harrison on The Drive on 610 Sports and said that Marty once pulled out old Chiefs-Raiders tape before they played the Raiders. The tape showed a Raiders player pulling legendary Chiefs QB Len Dawson off a pile and kicking him, which set the tone for the 1990s Chiefs-Raiders rivalry.
Smith also told a story about the time his Mom went to a game.
