So the main arguement of how Machida won last night is that he won round 1 and round 3. Round 2 and 3 are not question marks amongst everyone on these boards so lets talk about round 1.
Fight metric has Jackon landing more total strikes in the round while the more "significant" strikes went to Machida. Breaking the strikes in round 1 even further, Page hit Machida in the head 4 times and in the body 10 times where Machida hit Rampage in the head 1 time and in the body 3 times.
How are people arguing Machida won the round of all things? Shots to the leg are the only thing that Machida did better than Rampage in that round. Page was the aggressor, Page had Machida pressed up against the cage a significant amount of time. Page landed the most damaging strike in the round (shot to the face) and hit Machida in the head+body 14 times to Machida's 4. Page had far more octagon control where he was chasing down Machida and cutting him off, pressing forward for pretty much the entire round.
Leg kicks were the only thing Machida had over Page that round. Is that enough to win the round? Well there is some major hypocrisy going on around here and I am going to point you to it right now: FightMetric: Machida vs. Shogun FightMetric Report
Winning one round (round 3) does not entitle you to winning a fight. I would say convincingly
Rampage won round 1, with round 2 actually being the closest round of the three - which I still say Page won narrowly.
