I like Machida, one of my favorite fighters, but Lesnar should be able to run through his leg kicks and jabs and take him down and sit on him at will for all 15 minutes.
Lesnar has to catch him. Lesnar had trouble getting Randy down, and Tito Ortiz (who has better MMA wrestling than Lesnar) couldn't get close to Lyoto. Lyoto would run circles around him.
Lesnar would weigh in @ 265, probably 275-280 on fight night, and I can't see Machida being any more than 225 at the time of the fight, any more than that I think he'd lose a little bit of his speed and elusiveness.
tough call, Loyoto employs point-karate tactics and will do enough with his get in, get out striking to outscore Lesnar. Problem is I think Lesnar may have several inches in the reach department and cement blocks for hands. He just has to clip a small guy, like he did Randy and knock him down and pounce on him. I don't think Machida can get back up if Brock hops on top of him. Still the ultimate skill vs size/strength matchup for sure as Brock is a great athlete and not some mongloid like Hong Choi Man
