"One of the Lions' most interesting position battles in training camp will be between running backs Kevin Smith and Jahvid Best.

Smith is the third-year incumbent. He struggled last season, but he was a good soldier. He played hard and played hurt until suffering a torn anterior cruciate ligament in his left knee late in the season.

Best is the rookie highlight-reel speed merchant drafted in the first round after the Lions moved up to snag him.

But Smith isn't shying away from the competition, and he's not uncomfortable talking about it.

"I mean, I'm a competitor," Smith said. "It's not just Best. It's any back that's been in the backfield. I think he's a good addition to the backfield, and I think he'll be able to do some things to help us win games."

Smith even has a sense of humor about the competition. When Smith was asked how he felt being on the practice field with Best, he took it in stride and said their relationship is more collegial than competitive."
