Apples to apples or in this case playoff games to playoff games.Given that no goalie has even played 250 playoff games.Sonce Plante and Hall rank in the top fifteen GP the data is more than sufficient for playoff comparisons.
Which is why playoff games are often left out of the analysis, or at least aggregated with regular season totals. For the vast majority of players, there are just too few playoff games available to be of real meaning.
The shutouts give a true picture of the goalies performance against the better or playoff teams.
No, a goalie's save percentage against those teams would give a better indication of that. Again, why would you look at shutouts when you have other, better stats? Look at career playoff GAA: Plante 2.14, Hall 2.78. Do we need shutouts to know that Plante performed better in the playoffs? It's right there in the GAA. I'm sure it's in the save percentage too.
The shutouts give a true picture of the goalies performance against the better or playoff teams.
Why would we focus only on those 14 playoff game for Plante, and 6 for Hall? Why wouldn't we look at their overall performance, using save percentage for instance?
Another facet when looking at goalie comparisons would be in a historic fashion. Asking how many goalies and off what caliber position themselves between the two Plante and Hall in a key area. When app 25 sneak in the door then the claim of fairly close should be revised.
I'm having trouble parsing this, but if I read you correctly, GAA tells you everything that you say the shutouts do: Plante performed much better in the playoffs than Hall did.
Prime example being the SV% difference effectively the gap between .920 and ..917 is marginal yet if sufficient analysis using shutouts as a base then it becomes rather clear whuy Plante was the vastly superior goalie with the key honours.
Over 27,000 shots, a .003 difference in save percentage is worth about 80 goals.
So, basically Plante has somewhat better regular-season numbers than Hall, and significantly better playoff numbers. Aggregate them and Plante has better-than-somewhat-better numbers than Hall. And we don't need shutouts to tell us any of this.
Where have the shutout totals led us anywhere that save percentage or even GAA do not? For the record, Plante's playoff save percentage is .922 and Hall's is .911.
Now, your point seems to be that Plante's playoff performance prove that he is more better than Hall than their regular-season numbers would suggest. But have you factored in the fact that the average regular-season winning percentage of Hall's playoff opponents is .577, while Plante's is .525? Hall played against better teams in the playoffs than Plante, largely because Plante did not have to face the Montreal Canadiens.
Perhaps Plante recorded so many more playoff shutouts because he was playing against weaker teams.
