Subban hasn't gotten an invite for Team Canada which is a joke, Yzerman is an idiot.
No, but Canada has 8 Dmen now and has always been hesitant to replace a guy once the tournament starts except for injury. As Ruff said after they made their last addition (Hamhuis, who has WHC experience and was exactly the sort of veteran stay at home D that they said they wanted to add to their young squad) making any further additions isn't fair to the guys there and can be bad for chemistry. And any additions now means the added player will be in probably one game at most before the quarters.
