I love his stiff arm, his Hesteresque swith of gears, and the way he finishes runs but I think the way he jumps up after he is tackled and whistle is blown is what I love most. It is as if he is telling all those who tackled or hit him: I am coming right back at you. He does not help them up- he just springs up (always the first one up from the floor), barks some ****, and does it over and over again until the game ends. Duke has a little of every great cane in him. He is a walking version of all past great canes in one body.
