I've seen Toews take his game to another level when called upon. We've seen some glimpses of that from Kopitar but he also has a knack for disappearing for long stretches. Toews reminds me a lot of Doug Gilmour, he pretty much does it all for his team.
I know there are a lot of great goaltenders in the league, but I don't think there are any who make as many great plays in a row as flashy as Quick makes them look. He just makes them look great and spectacular.
