Taylor vs Kelly round 1 often gets overlooked. That was some crazy shit.
Does the Frye/Takiyama hockey fight round count?
Saku/Newton was a crazy 1st round too.
Few more i can think of Matt Brown vs "opponent that cannot be remembered" - Yves Lavigne lets Brown batter his opponent far too much and for way too long, that even Brown started protesting.
Machida vs Evans - Evans looked like he was turning into a serious striker until that point, then we learned what a serious striker was, epic.
Cro Cop vs Waterman - that image of Waterman trying to take Mirko down, and Mirko fighting him off by essentially pushing all of his weight on Rons chin, then soccer volleying him back into obscurity.
Maynard vs Frankie 1, round 1 - Immense
BJ vs Sanchez - round 4? (cant be 100% sure it was the 4th) - Watching BJ pace from side to side punching himself in the face and staring at Diego, then it was like he was unleashed and fucked the guy up.
Barry - Kongo round 1 - crazy
Randleman vs Fedor - The slam, the recovery, the sub, oooosh.
