Orima is kind of losing his aura here. I thought this guy was supposed to be basically this manga’s Kai Asakura: in his physical prime and ready to challenge the UFC (and lose to Tim Elliott there lol). I wanted to see him go beast mode at some point. Instead, he plays Aoba's game and looks like he’s one mistake away from getting submitted. Also, what surprises me is that he keeps escaping through physicality, even though his other big advantage over Aoba should have been superior experience. Like, Rd 3 should have been his battlefield with tons of traps for Aoba, not the other way around.
Wrestling is very physical by its nature, but it still requires a lot of technical expertise to avoid getting locked in a submission. Orima is certainly showing that he can skillfully avoid the various traps Aoba is setting which tend to be difficult to predict, and he's doing so where others have failed because they got blindsided by Aoba. So I'd say it does show how impressive he is.
He's not playing Aoba's game either; he's not trying to counterattack with a submission, his entire focus is in escaping and putting some distance to get back to striking. I don't know if that'll change now that he's locking in and no longer worried about pleasing the crowd by winning with a knockout.
I was thinking the same. If Aoba ever gets past his striking, he will have absolutely no clue what is happening. I guess the little training he's started doing for his ground game is still not enough, but I'm sure he's taking note of what's happening in this fight, which he doesn't understand, so he'll be a different beast whenever he does match up with Aoba.
He's also not Orima who likes to work the crowd and has incredible ground game in case he's ever caught; Kenshin is fast and furious when it comes to striking so Aoba might have an even harder time getting him on the ground. Good thing Aoba is showing he's super thick-headed with an iron chin and crazy recovery (though I don't know how long that'll last at the rate he's getting hit).
