Cowboys last traded down with a top-10 pick in '02, but dropped only 2 spots to take Williams at 8.
player they like a couple of spots lower. Then, maybe they could use their extra ammunition to trade up into the late first round and take someone else. Or they could use those extra picks to fill more needs than their current total (8) will allow.
Nothing reckless, mind you. Just never hurts to have options. And you can bet Jones will keep the phone lines open.
