Well ... hold on there a second. Of course this sort of thing comes down to years in the league and I've seen some better winning percentages. But for us lifers I got you beat.
Despite missing the play-offs and not knowing what the 2000/01 or 2001/02 record was (though it was one of those two years you and I met with the Wings going on) I've already got a count of 40 playoff wins.
2000/01 ??-?? (Conference finals?)
2001/02 ??-??
2002/03 15-13 (Cup Finals)
2003/04 06-07 (Conference finals)
2005/06 03-04 (Darn Wild came back fom a 3-1 deficit to knock me out early)
2006/07 10-06 (Conference finals)
2007/08 06-05 (Dallas, or should I say Kipper, took out Wings for 2nd year in a row)
2008/09 00-00
After adding in the info for the first two years I'm fairly confident it will be >50 wins
In 2009/10 Lidstrom will finally get his HFNHL Cup
