Agreed.
To me, handedness is extremely important for defencemen, and several posters have listed the obvious puck handling challenges of playing the off-side.
But to me, a defenceman’s play without the puck is even more negatively impacted when he plays the off-side, usually in ways most people do not even recognize.
Example: imagine you are a right-handed defenceman playing your natural side, skating backwards and maintaining tight gap control while defending the rush through the neutral zone. Where’s your stick? It’s in your left hand, protecting open ice (your body protects against anything wall-side).
Now, imagine you are doing the same thing but you’re switched to the left side (your off side). Where’s your stick? It’s still in your left hand — but now it’s board side. Your ability to protect the middle of the ice is severely compromised simply by the geometry.
Canada is going to ask every single D playing the right side to deal with this. There aren’t many Doug Harveys or Bobby Orrs — two masters at playing their off side — on Canada’s WJC roster.
I’m anything but a dinosaur, but handedness bloody well matters.
