Maybe the conspiracy theory is behind the coach's decision to bench Kaprizov. Why is he not playing Kaprizov if Kirill is an indisputably better player than the other 4 wingers for his position? Do you think that Vorobiev is utterly incompetent, or that he possibly bears a grudge against Kaprizov?
I think that a better player (on paper at least) doesn't necessarily become a more suitable cog in the team machine. Ovechkin is a great example of this since he didn't always produce abundantly for the national team. Another explanation for the Vorobiev's decision could be that he already knows what Kaprizov is capable of, so he decided to give other players some playing time. It's a long tournament, so we have to be patient.
