If Kent Johnson is stronger, he could play in NHL. Yegor Chinakhov will be more experienced. It'll be difficult for Kirill.
Btw, Chinakhow didn't play in KHL sooner only because Bob Hartley wants from players to be strenght too, he wanted to players be ready to play in KHL. And Yegor wasn't in that time. Look at Gritsyuk. He didn't play too much in the start of the last season but but gradually its time increased. Finally he was playing OG and was one of the best players, if not the best (after Fedotov).
