"Since Dexter McCluster is one of the smallest players in the NFL, the ongoing issue the Chiefs have is not just how to utilize him on offense, but also how much to play him.

He was a running back last year after spending most of his rookie season as a slot receiver. The results — he finished as their second-leading rusher and third-leading receiver in 2011 — would seem to indicate McCluster is better operating out of the backfield.

"The change to running back, I accepted it," he said. "I was happy to be a part of the running back group. I showed strides toward the player I'm going to be in the league."

Looking at next season, what to do with McCluster and how much to do is again an issue for the Chiefs. With Jamaal Charles coming back from torn knee ligaments and Thomas Jones and Jackie Battle unsigned, the Chiefs will need some help out of the backfield.

Chiefs general manager Scott Pioli, scouts and coaches spent the week at the Senior Bowl practices in Mobile, Ala., scouting some of the top backs available in the draft. Soon the Chiefs will have to decide whether they want to spend a premium draft pick on a running back.

Their backfield options will include Charles and McCluster, at least.

"Having Jamaal back will be great," McCluster said. "He brings the speed and the versatility you need in a running back. We'll keep a lot of teams off-balance.""
