Ortiz is a good fighter who has the necessary physical tools to make the fight competitive on paper, but no way he makes it the distance with Alexander, he would have some good moments early and I really like the kid and his story, but he'd get KO'd in 9.
Styles do make fights. I would need to see more of alexander just to be sure. However as it stands alexander showed plenty of power. Not maidana type of power which is what troubled ortiz. The speed would also bother him but then again ortiz has plenty of speed and power of his own. Hmmm I say its a toss up with the slight edge to ortiz. Styles make fights so I think maidana is actually a tougher fight for ortiz than alexander.
