That's not entirely true. Billy Smith elected in 1993. It wasn't until 2003 (Grant Fuhr) that another goalie got elected in to the Hall, that is a long time between goalies getting elected. Considering the less then 10 year gap in age of Price/Quick vs Lundqvist/Luongo and you consider that not as the same generation it is not out of the question that they skip a generation as they have in the past.
this is interesting. and good point about the '80s. the 50s were a really fallow period, where no north american was produced in north america for an entire decade.
birth years of hall of famers since the nazis invaded poland, with the biggest names after hasek added at the end:
giacomin 1939
cheevers 1940
esposito 1943
parent 1945
dryden 1947
smith 1950
tretiak 1952
fuhr 1962
roy, hasek, belfour 1965
brodeur 1972
luongo 1979
lundqvist 1982
quick 1986
price 1987
that is a huge age gap between smith/tretiak and fuhr. interestingly, exactly the same gap between brodeur and lundqvist. so you may be on to something.
but on the other hand, smith and fuhr played each other in the stanley cup finals twice. when smith won his vezina, fuhr was the runner-up.
if we look at it by time spent in the NHL rather than birth year, here's the tally of goalies building significant pillars to their HHOF cases, in five year increments:
'65-'70: hall, worsley, giacomin,
'70-'75: dryden, esposito, cheevers, parent, arguably giacomin
'75-'80: dryden, tretiak, arguably esposito (but probably not cheevers and smith)
'80-'85: smith, fuhr, tretiak
'85-'90: fuhr, roy
'90-'95: roy, belfour
'95-'00: roy, belfour, hasek, brodeur
'00-'05: roy, hasek, brodeur, arguably belfour
'05-'10: lundqvist, brodeur
so maybe the question is whether giacomin/cheevers is an aberration where a generation of guys peaking in the early 70s was overrepresented, or whether the gretzky era was the opposite aberration where nobody got in. which raises the question: is putting luongo in there for his '04-'11 stretch is a happy medium between how the HHOF treated those two generations?
the O6 "golden era" is really interesting to me. if you look at the 1960 season, all six starting goalies in the league were hall of famers: hall in chicago, plante in montreal, bower in toronto, sawchuk in detroit, and lumley in boston. if you go back to 1950, it's 5/6: brimsek in chicago, rayner in new york, broda in toronto, durnan in montreal, and lumley in detroit. it's stuff like that that makes me wonder how luongo, who is likely to finish 4th all-time in wins, with an outside chance of catching belfour for #3, out.
