Ultimately, it's not going to be a normal distribution, but (something) reasonably approximating the right-end tail of one. There are thousands of goaltenders out there who could post an NHL save percentage six standard deviations lower than the NHL average, and on the other hand, there are none (because none would get that opportunity).

The other poster is suggesting that it follows a power distributions, and he's probably right (I've written and spoke enough on the topic to know that power distributions handle outliers far more reasonably). I don't think that it matters too much in this context.
