Dunno why Anders Eriksson isn't on that list, he was absolutely atrocious. His game 6 giveaway cost us the series against Carolina back in the day too.
Raycroft was horrible too, couldn't stop a beach ball. Toskala was horrid but Raycroft took it to another level.
People forget how bad these players really were. Clarkson was by no means the worst Leaf. He was somewhat passable, just not even close to being worth the price tag.
Lumme wasn't THAT bad.
I'd say....Raycroft->Eriksson->Aki Berg.
Jason Blake was a blackhole as well but to be fair, he played on a horrid team.
