I have three at the top of the list right now. I like Chuck's TKO on Tito, Rich Franklin's knockout on Nate Quarry, and Melvin Guillard's knockout on Rick Davis.
As far as people I'd like to see get knocked out. It would have to be someone really cocky like Brandon Vera. After he won his first fight he called out Chuck Liddell and said after he won heavyweight belt he was going to drop down and take on Chuck.
Hughes slam on Newton rocked. I could watch it over and over. But I'd have to say the one that brought me the biggest smile was Ortiz getting Ko'd by Chuck. And I would give up all my posessions to see Ken KO Ortiz in October, but Im going have to wait until December to see Tito laid out. And since Ortiz vs Chuck is in December and so is the Hughes/Penn vs. GSP fight, will they be on the same card? That would be the PPV of the year hands down if so.
