It's interesting we have multiple posters saying Vernon didn't deserve the award in 1997, and multiple posters saying he DID deserve it (when he didn't win it) in 1989.
Vernon is sort of like Bernie Nicholls or Pierre Turgeon -- it's hard to get a read on how average / good / great he really was. I watched the guy play a LOT of hockey games (two or three times I watched him live at the Saddledome when I was a kid), and I still don't really know. I feel like blaming him for the early-90s' Flames' choke-jobs is unfair... but then again, he wasn't part of the solution either... except when he was.
Two remarkable things about Vernon: (i) he played for 4 NHL franchises, and had winning records with all 4 [how many goalies in history can say that, I wonder?]; (ii) he was the starter for two Stanley Cup winning franchises [also very rare, I'd guess, and puts him in some elite company].
I know it's not necessarily 'history' to talk about spring 2016, but do History-Board posters think Sid Crosby deserved his Conn Smythe last spring? I sort-of have a problem when a high-scoring forward doesn't score in the Finals and wins the Conn Smythe. It just seems wrong.
With Vernon, it's a little bit of a Giguere-like career. If you're just into "accomplishment counting" he looks really good. Stack up 2 cups, another 2 finals, a vezina runner up, a smythe, Those are all pretty good. But if you like consistent, game-to-game or season-to-season consistency, you're not going to like him. Those six accomplishments occurred in four seasons. 1989 was the only season he played at a level very much above league average (save percentage wise), and the four trips to the finals were only times he played more than 9 playoff games in a year. The dropoffs are just so drastic. Bill Ranford is another, as is Mike Richter.
Guys on the other end of the spectrum, who don't look great from an "accomplishment counting" standpoint, are Joseph, Vachon, Vanbiesbrouck, Lundqvist, Liut, Burke, Nabokov, and even someone like Vokoun, all of whom have less than 2 "accomplishments" (if you count a trip to the finals or a top-2 vezina vote an accomplishment) but were more likely to be better than Vernon if you just grabbed each of them on a random day during their careers, but for the most part didn't reach the peaks he very briefly reached.
