I personally wasn't disappointed by the fights. I wasn't happy with the outcome of all of them, but I thought all the fights were entertaining.
1st Fight - Houston Alexander is a Knockout Highlight Reel in Progress. Go to Youtube and lookup Houston Alexander vs Keith Jardine and you'll get more proof.
2nd Fight - What can you say about a guy who just about gets knocked out, then submits his opponent 2 minutes later
3rd Fight - I guess you can beat CroCop by kneeing him in the groin 5 times.
4th Fight - Hamill had the first round hands down. 2nd Round was close I thought. Hamill took him down once or twice, failed to advance, and Bisping was able to get out each time, and pressed the action. MMA judges value being the aggressor alot. Takedowns usually score well too, but only if you can advance your position. 3rd Round Bisping did control 2/3rds of the round (he took down Hamill Twice). Hamill Did take him down once, but again he wasn't able to do much with it. I personally agree that Bisping won it, but it wasn't what you would call decisive. And it sure wasn't 30-27 Hamill like that one judge scored it. Hamill is getting alot better, and he'll likely be a champ one day, but I don't think that he won that fight. If we're lucky enough to see a rematch, Hamill will probably win that one though.
5th fight - I was actually really suprised to see Rampage handle Hendo so well. Who'd've thunk that the guy that ko'd Liddell actually had a ground game.
That's my take on those fights. I watched Silvia and Arlovski jab at each other for 5 rounds. None of saturdays fights were disappointing compared to that.
