The fact that Subban's position on Team Canada has been marginalized is a reflection of the limitations of Subban's skating ability. He has almost no recovery speed and on the larger ice, that can be a fatal flaw. That flaw can be masked on the smaller NHL sized rinks. But on the bigger ice, Subban will be exposed.
The fact is, you have no idea what you are talking about. Subban's skating is what gets him out of problems not into problems.
