"At some point during the season, the Chiefs may not have enough playing time to keep running backs Thomas Jones and Jamaal Charles happy.

That's a situation of their own making, having been created last month when the Chiefs signed the veteran Jones to compete for playing time with Charles.

The Chiefs don't appear to believe it will be a problem - and, for now at least, Jones doesn't either.

"I don't think like that," said Jones, who last season with the New York Jets rushed for more than 1,400 yards and 14 touchdowns, both career highs.

"I feel like, by me working as hard as I can during the week to get prepared, I will be in a position to do what I need to help the team win. I have always been a team guy and for me, the more talented guys you have, the greater the chance you have to win. There is no perfect number of carries. It's what you do with each carry you get.

"I'm here to help the team win. If I get five carries, I get five carries. If I get 25 carries, then I get 25 carries. All I can do at this point is prepare for the season like I have always done. That is how I play and that is how I have looked at my career. I will continue to look at my career like that.""
