Yeah his stand up is dope but he is a typical karate fighter, similar to his stable mate Gunnar Nelson, and Gunnar got exposed by Rick Story. Karate fighters like Lyoto,connor and Gunnar Nelson, use foot work as their prime mode of defense. The problem with that is when someone can cut off the ring they become like fish in a bucket when their back is against the cage. Also he has a few losses by submission, but I think his ground game has come a long way.(Rumor has it, he has a pretty good Reverse De La Riva and butterfly guard) I think he might even beat Aldo(I think the fight is a toss up IMO), but I think he struggles greatly against guys like Mendes and Frankie, because they can pressure fight somewhat and they can set up their take down.
