Re: Ard-uscho poy
A part of the problem is that it's very hard to compare goalies directly to forwards or defensemen in meaningful ways. There are two main reasons for this.
The first is that goalies and skaters produce very different statistics. By that, I don't just mean that one is offensive, and the other defensive. That's true of the difference between hitters and pitchers in baseball, too, but in that case, a pitcher's stats are just the inverse of a hitter's: a single is also a single allowed; a stolen base is also a stolen base allowed. That makes it fairly straightforward to translate the value of a pitcher to the value of a hitter. Hockey goalies, on the other hand, don't have an inverse of many of the most important stats that skaters do. Shots attempted, which is probably the single most important team offensive stat, by a team are something over which the opposing goalie has little control. So, even before you try to tease out what a goalie's contribution to a team's goals allowed is relative to those in front of her, you have a basic translation problem.
The second is that a top goalie will play well over 90% of a team's minutes over the course of a season, while a top defenseman will play about half, and a forward closer to a third. This adds an extra step in trying to convert per possession stats into totals. It also means that we generally can't use the obvious step to try to control for the first problem: comparing how one goalie on a team does relative to the other goalies. The sample sizes for those other goalies are almost always too small to be useful.
Some work is being done to answer these questions at the NHL level, but there are a lot of reasons to be skeptical that the findings there would be relevant at the NCAA D1 women's level. The main reason to favor having a separate award for goalies isn't because goalies are underappreciated; it's because we currently lack the tools to adequately compare a goalie's value to a skater's. Let's work on getting defensemen valued properly relative to forwards, and defensive players relative to offensive ones, first; the methodological problems there are a lot simpler.
