It is difficult to rate all-time players due to the difference in eras and this is particularly true of goaltenders. My advantage is that I have actually seen all of the goalies play except Durnan and Broda.
Dryden would likely have ranked even higher but for his shortened career. For those who point to the Habs powerhouse teams as a reason for Dryden's record, check out the season he sat out in a contract dispute and did his articles as a lawyer. Without Dryden backstopping them the Habs looked more like the "Habs-nots". You can play firewagon hockey when you have a goalie who can make the crucial stop at the right time.
In so far as games played, particularly playoff games, Roy had a chance to play more than goalies of earlier eras where there were two rounds until expansion in 1967. The more games you play the more wins are possible so winning % and shutouts IMHO are a better gauge. Also you have to consider the quality of the team in front of the goalie.
As I said differing eras make it difficult to pick. IMHO Roy is not even be the best goalie of his era, let alone all-time.
Patrick Roy's stats ("#") = all-time record:
Reg season- GP 1029(1), W 551(1); Win% .618(80; GAA 2.54 (25); SO 66(3)
Playoffs- GP 247(1), W .611 (3) ; Win% .616(3) GAA 2.30(13); SO 23(1)
I think any consideration of top goaltenders would have to include the following. (I have watched all but Turk Broda and Bill Durnan):
Turk Broda - 5 Stanley Cups with the Leafs, often considered the best clutch goaltender of all time.
Reg Season- GP 629, W 250; Win%.571 GAA 2.53; SO 62
Playoff -GP 101, W 60; Win% .594 GAA 1.98; SO 13
Ken Dryden- 6 Cups in 8 years
Reg Season- GP 397, W 258; Win% .798; GAA 2.24; SO 46
Playoff -GP 112, W 80; Win% .714 GAA 2.40; SO 10
Glenn Hall- 502 CONSECUTIVE STARTS - the first real butterfly goalie - not Roy.
Reg Season- GP 906; W 407; Win%.548; GAA 2.51; SO 84
Playoff -GP 115, W 49; Win%.426; GAA 2.79; SO 6
Dominik Hasek- 6 Vezina trophies and 2 Harts, 1 Stanley Cup and Olympic Gold. Enough said.
Recorded 6 shutouts in one post season.
Reg Season- GP 581, W 288; Win%.574; GAA 2.23; SO 61
Playoff -GP 97, W 53; Win%.546; GAA 2.03; SO 6
Jacques Plante- 6 Stanley Cups, 1 Hart, 7 Vezinas
BTW Clint Benedict not Plante was the first goaltender in hockey history to don a facemask in a National Hockey League game, February 20, 1930.
Reg Season- GP 837, W 434; Win%.628; GAA 2.38; SO 82
Playoff -GP 112, W 71; Win%.634; GAA 2.16; SO 14
Terry Sawchuk- 2nd in GP and Wins - 103 SHUTOUTS
Reg Season- GP 971, W 447; Win% . GAA 2.52; SO 103
Playoff -GP 106, W ; Win% . GAA 2.55; SO 12
Also consider where you place the best goalie who never played in the NHL - Vladislav Tretiak.
As I noted IMHO Roy is not even the best goalie of his era. I give "The Dominator" the nod over St. Patty. It may well turn out that Brodeur will surpass Roy - I rank them about even right now.
Here is my list:
1. Terry Sawchuk
2. Jacques Plante
3. Ken Dryden
4. Dominik Hasek
5. Glenn Hall
6. Turk Broda
7. Patrick Roy/Martin Brodeur
9. Bill Durnan
10. Vladislav Tretiak
