It's systematic from fans of the Maple Leafs. Whereas Canadiens fans were too unmoved to bother expressing opinions on the Leafs latest playoff-eschewer-to-be last season, there's hardly a Leafs blog worth its weight that passes up Martin bashing. I think it's essentially because Leafs fans, young ones especially especially have built their identities around two fundamental truths:
1) That beating Ottawa in 4 consecutive playoff series was the best thing about their decade
2) That 1993 was their year, cheated only of their latest Cup by foul refereeing
... I suspect that if a psychoanalyst were to probe into Toronto's complex about Jacques Martin, they might find a more profound complex about the falterings of Pat Quinn with sometimes superior and often more playoff-ready contending teams. (I suspect they'd have a lot to say about me writing this article about Toronto's complex too...).
