He's only 'legit' until his next fight. I think that word is not a good way to describe someone in MMA. Each fighter has their own unique skill-set and some of it matches up well with a fighter and the reverse, but I think come fight night it boils down to who's the better fighter on the night.
I don't think Ortega is any more legit now than he was before the Edgar fight. He cracked Edgar with a nice left hook or straight that wobbled him and what impressed me about Ortega was his composure where he didn't rush in once he seen Edgar was wobbled.
In contrast, earlier in the night in the O'Malley and Soukhamthath fight, the latter got dogs abuse for taking it to the ground and his fight IQ was questioned. I agree fully with folk saying he should have let O'Malley get back up, but there must be a million things rushing through certain fighter's heads when they're in there and I'm sure Soukhamthath will be kicking himself for taking him down. I think that's a fight both of them can learn from. O'Malley looked good, but he seemed to rush things a little bit, while Soukhamthath stood in the pocket and then was snake charmed into putting pressure on O'Malley without throwing much and got caught.
I think a fighter keeping their composure is one of those things that's over looked and Ortega seems to have that - not that he can't lose it in a fight in the future. Even when he fought Guida, I thought he was 2 rounds down and then he landed that jumping knee that KO'd Guida.
Now he'll have a lot more distractions outside of fighting that might be a pain in the balls to deal with and he may need to start think-thanking how to deal with all that.
