I wasn't exactly looking forward for the main event as their first meeting was really disappointing but the co-main event was great! It was a short match and it appeared as if Toney was just standing there and waiting to release one power shot to beat Couture. But Couture just went for an ankle takedown, did some ground and pound and eventually submitted Toney via triangle choke.
This however does not prove or mean MMA will always win against Boxing. The winner is determined by what rule will be applied. If an MMA fighter goes to a boxing match, the boxer would be 99% (if not 100%) win that. What this showed however is that some boxers are getting interested in MMA because of the quality fights being made there. Unlike in boxing nowadays there is almost nothing good to watch. If I recall correctly, Toney himself said that boxing doesn't offer him great fights anymore and since UFC is putting great fights he tried it out. Big credits to Toney for stepping up and backing his words.
As for the main event, it was just painfully boring to watch. Penn looked like he was confused and as if his mind is on another dimension. Edgars style was not that exciting at all even though he dominated Penn for full five rounds. Other than Edgars ability to move in and out fast and take less damage, the other reason why Edgar won again is because Penn clearly has lost that "killer instinct" that he had for so long. If you go back and watch Penns old fights, you'd probably say that Penn of today is just a look-alike. Penn really looked as this was his first MMA fight and Edgar just took him down at will.
Another interesting fight was Diaz vs Davis. Quite ironic that the former boxer (Davis) was out-punched (if not out-boxed) by Diaz. It's just a sad journey for Davis. He had a lot of good fights and wins along the way but everytime he comes close to a title shot, he loses.
Lastly, it's as if fate had this planned all along --- Meynard vs Edgar 2. During their last outing Meynard beat Edgar via decision. And now, Edgar has the chance to avenge that single loss and of course Meynard has his chance to become the next UFC lightweight champion.
