Pick a streak. Any streak. If it's bad, the Oakland Raiders may have just snapped it. Getting 139 yards rushing from Justin Fargas and a big defensive stop on fourth down, the Raiders handed the reeling Kansas City Chiefs a 20-17 defeat Sunday that ended three different kinds of football failure. Until those final seconds ticked away, the Raiders had lost 17 straight AFC West games. They'd dropped nine in a row to Kansas City. And, they'd also lost six straight overall.
