I think you need more data to analyze hockey correctly.
For example to evaluate goaltending you need to quantify "shot quality" in some meaningful way. In doing so, you are inherantly building in some type of bias. If you are aware of the bias (or believe that your "shot quality" ranking scheme is infallable), then you can statistically evaluate goalies.
To evaluate any skater, you need to quantify defensive ability as well as offensive production. A form of "blame/reward" +/- is probably the way to go, but again requires individual scouting and potential biases of the evaluator. To take it a step forward, combine a "blame/reward" system to the "shot quality" ranking, and you might have a chance.
But pts, +/-, GAA, sv%, etc are all flawed metrics that are nearly useless in evaluating players I think.
