Alex Smith: 'Kansas City Chiefs have a great balance'

Alex Smith has said that the Kansas City Chiefs' "great balance" has helped them to an unbeaten start this season.

The AFC West side, who finished last year with a 2-14 record, beat the New York Giants 31-7 yesterday to maintain their 100% start to 2013.

The quarterback told reporters: "I think it's a strength of ours. We continue to have such great balance to be able to do some of the different things. Yeah, I mean, guys are stepping up.

"We had some injuries at the tight end position and those guys are stepping up and playing good football. Jamaal [Charles] is so versatile, in and out of the backfield, running and catching, it was really a weapon for us.

"Then outside, Donnie [Avery] with the amount of catches he had last week, I think you could definitely tell they recognised that and Dwayne [Bowe], on the other side. I think the more balance you have with the guys outside, the better and the tougher it is to defend."

The Chiefs play the Tennessee Titans on Sunday.
