Nobody has asked what type of league you are in? Given the categories, it's not the league in your signature. Their values can change depending on whether it's a H2H or Roto league. For example, in a H2H league shutouts are devalued as they happen randomly and infrequently, so they won't have as much of an effect on your weekly matchups. In a roto league, they are much more important as every shutout has a significant effect on the standings.

Furthermore, generally I feel they all have value for several years so being a keeper league doesn't have as much of an effect on me. And given that many goalies' performances can fluctuate yearly, I'd prefer to look more in the short term.
