In the early 90's the Red Wings were like the Leafs of today: big winners during the regular season and absolute playoff chokers. Back then, beating Detroit in the playoffs was no great accomplishment. They were a mirage until Scotty Bowman showed up. The 93 Leafs only finished 4 points behind Detroit so it wasn't a huge upset. They also finished well ahead of both the Blues and the Kings that season.
And don't come and try to convince me that the Leafs weren't heavily favored to beat Vancouver in 94. The Canucks were barely a 500 team that season and had they played in the Central Division with the Leafs would have finished in 5th place out of 6 teams.
