The Facts: The Chiefs and Williams have agree to terms on a 2-year extension, Williams' agent announced on Twitter.

Diehards Line: Williams gets a max value of $8.1 million on the extension. He’s eclipsed 100 yards in each of the last two games and even with Spencer Ware working fully this week coming off a hamstring injury, it seems safe to assume Williams will continue to play a signicant role in Kansas City's offense going forward.
