You still didn’t explain what I had asked. Why would only one be a starter? To begin with, Vasilevskiy and Bobrovsky are starters right now on big contracts that they’ll still be paid in seven years. I’m not sure why they wouldn’t be starters in seven years.
And even past those two, you’d be assuming none of the others pan out. Aside from Hart and Knight, Askarov, Shestyorkin, Sorokin and Samsonov are the four best young goalies in the world. Russia has four of the best six, so it seems pretty likely that if a few of the young goalies pan out around the league, it’ll be a few of those players. Being a starter for seven consecutive seasons isn’t that big of an ask. I counted 12 goalies in the league right now who’ve been starters for the last seven seasons.
