Quick isn't that good, but unfortunately people (as you can see here tonight) will base their observations on small sample sizes.
When Quick has another sub .920 sv% regular season, people will still say that he "gets it done" and is "clutch.".
Out of the 7.5 million (peak viewers) of Game 2, how many actually know hockey? Quite a few, but probably they are the a very major minority. They just care about the favourite, and the players that are showcased and presented to them glowingly. It's exciting for them.
We know it's just showtime for the NHL, so I don't think we should be surprised. Even though we know his stature, Quick is still good enough to get it done for the team he plays for. That is also a fact, so you also have to understand that he looks more successful, right?
