I know I'm setting myself to get ripped by those who hate our team in every way but I don't feel as though Price has ever really played as well as he is capable of during the playoffs as he did during the regular season 2-3 years ago as well as during both his Olympic journeys.
The reason I say I'm setting myself up is because the obvious reaction is that the Habs aren't as good on paper as team Canada. With that being said, I feel as though there's more to it than that.
It's a great argument to state that other goalies can counteract the Price effect in a 7 game series but on the other hand, I feel as though if you truly are the greatest, you should be able to rise above the enemy and play better than them at all costs. That's certainly the mental part of the game rather than the skillful part of the game and while I don't doubt him in any way, I will say as a coach (of a different sport) myself, hopefully Price has that innate mental edge. His skills are there but if other goalies are matching him, it's because of their mental compete level.
That's food for thought in and of itself but on topic, I don't think there's a set formula. If anything we could perhaps argue that goaltending in general is getting better and so there's quite a bit of parity in the position. If I were building a team, I'd have very little issue with my goalie being my best player. I'm personally comfortable with that. Is it only an old school way of thought? I don't see why it would be. The only negative I can think of is that your contract is likely to be high when they are a sure thing and so another team can luck out with a decent contract and more offensive power.
