I was looking at this about a week ago and noticed the same problem. Virtanen and Gaudette's big improvements are the main "problems". Don't get me wrong, it's a great problem to have, but I do think @Provost is on to something. Losing Tanev and replacing him with either Tryamkin (who I think is far less of a certain thing than some do) or Rafferty is a monstrous loss. Those two kids aren't in the same universe as Tanev right now. That said, it's plausible that Rafferty could replace Stecher, and I think he probably will, due to the aforementioned cap concerns. I think Tryamkin may not work out in the NHL, as I'm not sure his desire to make it work is strong enough.
