Cowboys showing rare signs of being defined by defense first

Sean Lee wants more time to decide if this is the best chance the Dallas Cowboys have to be defined by their defense in the linebacker's eight years with the club. The Cowboys (1-1) are fourth in the NFL in total defense, with a loss to Carolina that could have been a blowout and a win over the New York Giants that wasn't nearly as close as the seven-point margin. ''I think we're starting to show the type of defense we can be,'' Lee said Thursday.
