Spiller believes he can revitalize his career in Kansas City, Terez A. Paylor of The Kansas City Star reports.

Once viewed as an upper-tier fantasy back, Spiller has been a major disappointment the last two seasons. He's bounced around among the Saints, Jets and Seahawks during that span, playing in 19 games and averaging just 3.1 yards per carry. In addition to his lack of productivity, Spiller has dealt with a myriad of injuries, including a knee issue that required surgery in 2015. After inking a contract with the Chiefs in February, the 29-year-old believes he's as healthy as he's ever been, but he may need a standout training camp to earn a spot on the 53-man roster. Though the Chiefs bid adieu to longtime bell cow Jamaal Charles, holdovers Spencer Ware and Charcandrick West and second-round pick Kareem Hunt will likely open camp ahead of Spiller on the depth chart.
