What does the other end of the table look like - who are the "Wins Subtracted" leaders for a single season and from 88-present?
Careers, 1988-present
Goalie|Decisions|Wins Subtracted
Marc Denis | 314 | -12
Kevin Weekes | 292 | -12
Damian Rhodes | 296 | -12.1
Craig Billington | 265 | -12.3
Steve Passmore | 79 | -12.6
Kirk McLean | 607 | -13
Pat Jablonski | 107 | -13.1
Patrick Lalime
| 377 | -13.8
Grant Fuhr
| 589 | -14
Peter Sidorkiewicz | 237 | -14.8
Glenn Healy | 417 | -16.4
Tim Cheveldae | 343 | -16.7
Dan Cloutier | 317 | -17.7
Don Beaupre | 388 | -18.2
Jeff Hackett | 471 | -18.3
Rick Tabaracci | 254 | -19.1
Tommy Salo
| 512 | -19.3
Garth Snow | 327 | -19.8
Jamie McLennan | 238 | -20
Chris Terreri | 372 | -20.8
Generally these are career backup goalies but there are a few exceptions. Salo seems much lower than he should be (IMO) but his solid years in Edmonton can't offset poor play during the rest of his career. Keep in mind that Fuhr's numbers are only from 1988 onwards; his best years are not taken into account. Lalime is a classic example of a goalie that gets overrated because he won a lot of games on an elite team; he won far fewer games than he was expected to while on the Senators.

Dan Cloutier | 2000 | -7.5
Peter Sidorkiewicz | 1993 | -8.1
Patrick Lalime | 2004 | -8.2
There are some pretty good goalies on this list. Peeters was way past his prime by 1990. The young Fleury rebounded nicely (-6 wins in 2006, then +7 and +3 the next two years). Nabokov, as I wrote about earlier today, is inconsistent but is a legitimate Vezina candidate when he's on. Don't take Kolzig's appearance too seriously -- he only played 14 games that year but his 2-8-2 record got prorated to something nasty because it was the lockout year.
Dan Cloutier posted a 9-30-3 record for the 2000 Lightning. That was a bad team, but he was still expected to win around 43% of his decisions (vs 25% in reality).
Peter Sidorkiewicz played on the expansion Senators in 1993. The numbers say that the Sens were below average (but decent) defensively, but keep in mind this doesn't take shot quality into account. Based on watching the Sens I have little doubt that they were, no better than the second-worst defensive team in the league. I'm not saying that Sidorkiewicz was a great goalie, but after 64 games on an expansion team that allowed countless breakaways and odd-man rushes, he's better than his Wins Added indicates.
The 2004 Senators were the best offensive team in the league, and were 3rd best defensively. Lalime was expected to win 67% of his starts and went just 25-23-7. (I don't think a 67% win expectancy is unrealistic, either, considering that career backup goalie Martin Prusek won 70% of his decisions, going 16-6-3).
