It's not unusual for players drafted in the NHL who are evolving in the KHL to be treated differently by their coaches. We often see these players get benched during games, as their development isn't a priority for the KHL. That seems to be Demidov's case.
In the first 10 games of the season, Demidov's ice time has ranged from seven to 14 minutes, but last game, he was only on the ice for 4:07.
There's no doubt that it would be beneficial for his development. As of now, Demidov is set to come to Montreal after the current season, but if this circus continues, the Canadiens could be forced to make a move.
