Marquez i think it would resemble Marquez-Diaz 1. Ortiz gets out to a fast start and bullies Marquez against the ropes. After about 4 rounds JMM starts turning it around and never looks back.
then you move the thread to MM :: Ortiz beats Marquez by a very wide margin today. I'm not convinced that Marquez is the least bit effective at any weight beyond 135.
Ortiz is too big for him and Marquez doesn't have that speed to catch him with shots he doesn't see. Manny however would ICE Ortiz.
