You can hear the laugh across Lake Lanier.
"I've always thought I was good," says Michael Turner, sitting on the bow of his 20-foot Ranger a week before training camp. As he gazes at Georgia's largest lake between casting fishing lines, the Falcons running back unleashes a cackle that sounds not unlike an old pickup truck trying to turn over in the dead of winter.

Something like self-doubt.
