not to mock what your doing, its a great idea. If i were you (which i am not) i would go further, and also focus more on just the NJ Devils.
Also your focus is a bit too much on just the Goalie. It would be nice if you gave the defense some responsibility.
But google sheets would be best as multiple users can edit.

For a few years, I had a website, that simply had a dropdown of the devils roster, and a drop down of values from -5 to 5.
So when a defenseman lost his man, he would receive a negative 2. If it lead to a goal -4. If a player receives sauce for a tap in, he would get 1 point, and the apple (assist) would get 2, and the person that did the work. Players got points even for creating chances.
I then had a reporting page, where you can pick player(s), and see a grid, you actually could see Zacha trending up as well as McLeod and the down fall of cammalleri, before regular people really started to notice
