It is difficult to imagine that the Avs would insert him in the lineup in the middle of the playoffs, but they did insert a rookie straight out of college into their lineup without hesitation.
It does seem like they are getting Kamenev ready. I wonder if he could replace a Brassard in the lineup.
I sometimes have the the impression that the Avs like certain young players within the organization and they want to give them a taste of the playoffs to further their development.
I don't think they should insert Kamenev in the lineup at all. Simply because he's going to be beyond rusty and will most likely be an even bigger detriment to the team then Brassard because of it. Nemeth and Andrighetto are both better options than him.
