I have been asked in the comments to list my top all-time goalies just as a reference point for my analysis on this blog.
My overall premise is that in the majority of cases, the goalie is as good as his team. When I evaluate somebody, I am looking for evidence that they were better or worse than the team around them. I don't care very much about things like wins or shutouts or Cups, as they are very strongly influenced by the team. Instead, I prefer to focus instead on save percentage, individual awards, playoff performance, performance relative to era, and performance relative to teammates.
All-time rankings are always a tough task because of different eras, incomplete historical information, uncertain team contexts, and other challenges, so it always comes down to a bit of guesswork. I am pretty settled on my top 4 guys, but after that I'm still trying to sort out the rest. I tend to think that ranked lists are very subjective and often not very meaningful (is there really a big difference between, say, the guy ranked 12th and 13th on pretty well any list?), so I present my top 4 ranked goalies along with a list of honourable mentions to others who are also in the argument.
1. Dominik Hasek
Most MVP awards by a goalie, most times finishing first among all goalies in MVP voting, highest career save percentage, best official single season save percentage, best ranking compared to his backup goalies, 6 Vezina Trophies.
2. Jacques Plante
Did very well compared to his backup goalies throughout his career. Played on some great Montreal teams, but his late career performance with St. Louis and Toronto was also outstanding. Has a very good playoff record. Won a Hart Trophy. Tied with Hasek for most times leading the league in "Goals Saved".
3. Glenn Hall
Named the best goalie in the league seven times in end of the year All-Star balloting, more times than any other goalie. Wasn't as outstanding in the playoffs, but his teams were likely a major factor.
4. Patrick Roy
The performances of his backups indicate that he was definitely helped by his teams, but Roy still has an impressive record: Excellent playoff resume, very good era-adjusted save percentage results, and 3 Vezinas and 3 Conn Smythes that suggest a strong individual contribution to his teams' success.
Other goalies I think were very good include: Bernie Parent (very high peak value), Ken Dryden (not completely sold on him because of the huge team effect, but his performance numbers are outstanding), Turk Broda (exceptional playoff performer), Tony Esposito (great regular season play makes up for lack of playoff success), and Johnny Bower (did well in save percentage stats put together from the Original Six era).
