Aoki for what it's worth won't come to the UFC because Japanese MMA fans are feeling very betrayed lately with Ishii and Akiyama both leaving Japan and Aoki doesn't want rumors to start he will leave to.
I'm sure Aoki wants to fight BJ and I can't blame him.
Personally I think BJ would be too much for Aoki because his submission defense would be too much and standing he will out strike him however I'll be honest I pick against Aoki when he's facing well rounded fighters and I've been wrong twice.
And honestly I'll pick against him if JZ vs Aoki 3 happens.
Another things people talk about how Japanese fighters are overrated but honestly guys the entire LW division of MMA is loaded and it's not because guys are fighting in Japan that they are being exposed it's that the LW division has so much talent that guys like Stevenson get exposed and fall off the map.
Also I think it's unfair to say that guys get overrated just because they fight in Japan. UFC fighters get overrated all the time also for every Sokky you have a Houston Alexander.
