If you have no experience in wrestling/submissions, then I can see where you wouldn't find it entertaining, but I personally would rather see a good submission than a KO. Many of the sports hardcore fans have usually trained in wrestling or some othe martial art that focuses on submissions and where you see two guys rolling on the mat they see the science and skill envolved. Entertainment is purely subjective. Chuck has several options in front of him for future fights. There is the fight with Silva, a fight with Griffin, a rematch with Quinton Jackson and a fight with Rashad Evans. If UFC runs out of fighters they simply go out and sign somebody new, or use one of the Ultimate Fighter contestants.
