…swept a seven game playoff series.
…won a seven game series in five games (until this year).
…won the first three games of two consecutive series (until now).
…won the first three games of any seven game series before this year. (They have only won the first two games in a series twice, before this year: 1968 and 1976.)
…had a 7-1 record after eight playoff games (until now). They were 5-3 to start 2001, 1993, 1991,and 1976; 4-4 to start 1990, 1989, 1982, 1977 and 1969.
…won consecutive seven game series in fewer than 12 games (1993, rounds one and two in 6 games each).
…won consecutive playoff series, except for 1993, when they won three.
Bonus late night numbers: after the first eight games of any playoff year, the Kings are 11-26 (disclaimer: I might have miscounted, so don’t quote me). It wasn’t until one of those Gretzky years (1991, I think) in which they finally won a game after the first eight (game 6 in the second round). Before 1991, the Kings were 0-12 in playoff games after the first 8 games in any post-season. Most of the wins (8 of them) came in 1993. Two came in the 2001 Colorado series. I’m tired and bleary-eyed, but I think these numbers are right.
