Dempsey did more than rock him in round 4, he almost had him down(No I dont think Tunney would have stand down lol) But Tunney grab onto the ropes thus stopping his fall and back peddle to safety before taking full controll over the round. Tunney did start backing Dempsey up onto the ropes and pounded him there in the later rounds though of fight 1. The "Real" round ten shows a other story(Kings of the ring) than round 9 poses as round ten like espn classic mixing rounds.
