Here's how Roy and Hasek rank in Goals Versus Average (which combines save percentage with workload):
- Roy - 1st (1989), 1st (1990), 1st (1992), 2nd (1988), 2nd (1991), 2nd (2002), 3rd (1987), 3rd (1994), 3rd (1997), 5th (1998), 6th (2000), 6th (2003), 7th (1993), 7th (1996), 7th (1999), 10th (1995)
- Hasek - 1st (1995), 1st (1996), 1st (1997), 1st (1998), 1st (1999), 2nd (2001), 2nd (1994), 7th (2006), 8th (2000), 10th (2002)
If we cancel out similar finishes (and I'll also cancel out a 7th for Roy with an 8th for Hasek), and we're left with:
- Roy - 2nd, 3rd, 3rd, 3rd, 5th, 6th, 6th, 7th
- Hasek - 1st, 1st
There's a much wider range in how goalies perform from year to year, compared to skaters. Roy brought enormous value to his teams by being consistently excellent year after year. From 1987 to 2003 (a span of 17 seasons), he placed lower than 7th in GVA only twice. I'm not saying that's the same as Gordie Howe with 20 straight years in the top five in scoring, or Ray Bourque with 19 out of 22 seasons placing in the top five in Norris voting - but it's not far off either. Would you trade someone with two scoring titles and little else (ie Dickie Moore) for someone who was a top 7 scorer eight times (ie Joe Sakic)?
Just to show Roy's consistency. From 1980 to 2022, here's how many times each goalie placed 7th or higher in GVA (granted an arbitrary cutoff) - Roy did it 15 times. Hasek and Luongo are next at 8 times. Lundqvist and Vanbiesbrouck did it 7 times. Brodeur 6 times. Then Joseph, Barrasso, Hrudey and Moog five times each. It's a very tough standard (Belfour and Price don't even qualify).
You can say I'm being disingenuous because Hasek clearly peaked higher. And that's true. Hasek has all five of the highest seasons in GVA between them (then Roy has 9 of the next 12). Can you argue that Hasek's peak trumps anything Roy ever did? Possibly. If the question is who's the "better" or more naturally talented goalie, I think it's almost impossible to choose Roy.
But if the question is "greatest" (which is generally how we make our top X lists), I'd go with Roy. Hasek has the higher peak, but Roy ends up ahead in career GVA. He was much more consistent from year to year (which is rare for a goalie). He still led the league in GVA three times (so he wasn't a compiler - and nobody else from 1980 onwards has done this more than twice). And Roy's playoff resume is vastly superior (where, adjusted for era, he stopped the puck more effectively than Hasek, over a much larger number of games).
