That's Guentzel - a rookie - saying that.
Repeating as champion is really hard in any sport, but particularly in hockey. The Fleury redemption story is buttressing their desire to repeat. Removing that risks a lot, even if Murray is better, when you are making the decision on one period of play where they, the defense, hung Fleury out to dry.
I think you are underestimating their ability to play as professionals. One of their best players is out, and they have been able to win. Or do they not like Letang? Hell Dupois had to quit hockey and this team won. You are overplaying the emotion big time.
