On the Perfetti thing, Bowness specifically said they want a guy with more size along the boards vs. Perfetti. That's the idea. He likes size for its own sake.
Yeah - I think he was referring to board battles.
That can certainly be debated - he appears to want a more defensive approach late in the game.
Right or wrong, I think he's trying to address the situation we often find ourselves in late in games when the other team is pouring it on and applying pressure in our zone. He wants the puck back and cleared - he feels the heavier guys have a better chance of making that happen.
IMO, our top six guys come up short in that area - they have the skill but they don't always apply the effort defensively, compared to some of our bottom 6.
I don't think he makes decisions for his own sake - he makes them based on what he feels will be most effective in certain situations.
Cole is not his choice in defensive situations as described above - that can be debated but I don't think it supports a statement like "he prefers size over skill" - maybe in some situations but that's not how he manages the team over all.
