C.J. Spiller gladly accepted Fred Jackson's challenge. And this time, the rest of the Bills -- on offense, defense and special teams -- showed up to support Spiller, who scored twice and finished with 123 yards rushing to spark a 35-17 win over the Kansas City Chiefs in Buffalo's home opener. It was a much better effort than how Buffalo opened the season with a bumbling 48-28 loss to the New York Jets last week.
