Victor Ortiz is considered a bigger underdog than Marquez! What are your thoughts?

Based from the past performances of these fighters, I would say that Manny Is having a more competitive fight against JMM. Marquez lost a very close decision to Pacquiao and although the fight this time would be on a catchweight of 144#, it is still within his fighting weight since he will come in way above that come fight time. Ortiz won just one notable fight since he fell out of favor from his promoter and that is against Andre Berto. Prior to that, he got a draw against Peterson and his performance is not on the level that can be expected from a fighter who was consider a bright prospect although his fight with Berto is an eye catching one. His loss to Maidana really damage his reputation that up to now wasn't in the former self even after winning the title in his last fight. Victor might be a champion but still untested up to this point of his career.
