This is pretty easy to break down, Kazama is not very good. He is supposed to be a grapple first guy and hasn't been able to get his grappling going in the UFC. He isn't offensively dangerous enough or defensively tough enough to get through this. Charalampos should win here and he is the pick.
Charalampos Grigoriou
Charalampos Grigoriou is a powerful striker with heavy leg kicks. He absolutely chops down the tree and can win fights from there. He can grapple as well with big takedowns and heavy top pressure. Overall he is a solid prospect who can win fights both on the feet and on the ground. He is coming off a loss to Chad Anheliger in his UFC debut where he got the wrestling going, but couldn't find his rhythm on the feet.
Toshiomi Kazama
Toshiomi Kazama is a solid grappler who lets his hands go on the feet. His takedown defense can use some work but even when he is taken down he has slick enough BJJ to scramble, sweep or even submit. He is a grapple first fighter and can be a bit chinny on the feet. He is coming off back to back first round TKO losses, the most recent to Garret Armfield
