KANSAS CITY, Mo — Final score: Boring Game Manager 26, Gnarly Swashbucklers 15. Yes, Alex Smith beat the Raiders at Arrowhead again. The Raiders might never forgive the 49ers for kicking Smith out the door in favor of that new kid, Colin Kaepernick, back in 2013. On Sunday, Smith game-managed the Raiders into oblivion with a ho-hum, 20-for-34 day, 268 yards and a 71.7 passer rating, far below his season mark of 107.2, which is higher than he has ever finished for a season.
