Rothenberg had a longer interview these days in which he also spoke about Michkov. In summary he said that Michkov is too good for junior hockey and therefore no longer plays there. In his opinion he still lacks the physique for men's hockey. Especially his legs are not trained well enough. He always refers to Kaprizov or Marty St.Louis in conversations with Michkov, who have massive legs and should be role models for Michkov. Rothenberg had also given him instructions for the summer, which he apparently didn't quite follow. Otherwise, in his opinion, Michkov already has the best scoring instincts of any player in the world.
His priority at the moment seems to be at physical training and a game here and there. But the season has been going on for a good three months and Michkov is down to only 8 full reg games... that can't be in anyone's interest.
