Gotta disagree - the "0" is still there because he has not fought a top level fighter... ...yet. I wouldn't jump on that bandwagon until after the FE fight this Saturday. I think people often overlook the fact that FE should be fighting at 35; but has won a belt at 55 and would already be a 45 lb champ but Aldo just had his number. He's always been undersized but wins on heart and skill.
Not too sure how Ortega's grappling skills will pan out against a Div I / BJJ practitioner. I don't see a sub happening at all; just failed sub attempts. I'd have to look at his standup again before placing any wagers but I don't think Ortega is a very polished striker.
