I'm not sure it's even possible to have a both skill sets that good. If that fighter ever comes around, god help the rest of them.
He's a disciple of Minotauro so who knows. I doubt his ground game is THAT good mostly because his hands are downright freighting but I'm sure it's not too shabby. All I know is he has a black belt so he's clearly not gonna be in uncharted waters if he does get put on his back.
Cain better hope and pray he can get this to the ground quickly and keep it there, injured or not he doesn't have the chin to get through the type of fight everyone wants to see with Junior, if Cain wins it has to be a one sided fight in his favor and I don't know if anyone can do that to Junior.
