November 13, 1997: Days after GM Pat Quinn was fired, Head Coach Tom Renney and Assistant Coach Terry Bangen are both fired. Mike Keenan is hired to replace Renney, becoming the 14th Canucks coach in history.
In 101 games coached, Renney lead the Canucks to a 39-53-9 record, missing the playoffs in his only full season. That team had a good deal of promise - Mogilny lead in goals, Gelinas, Bure and Mike Ridley weren't far behind in points - but couldn't make it work on the ice. Renney would resume his coaching career with the Rangers in 2003 and had far better success until he was relieved of his position this past summer. He's now an assistant coach (and Pat Quinn the head coach) with the Oilers.
Terry Bangen, as best I can tell, is currently the Director of Player Personnel and Assistant GM with the Tri-City Americans of the WHL.
Iron Mike didn't fare much better. In his season and a half with Vancouver, he coached 108 games and ended up with a 36-54-18 record. His GM record is hit or miss, but as his first act as head of a five head GM consortium (along with Steve Tambelini, Mike Penny, Steve Bellringer and Stan McCammon) they moved Kirk McLean and Martin Gelinas to Carolina for Geoff Sanderson, Sean Burke and Enrico Ciccone. Fun fact: all three players Vancouver received would be gone by the trading deadline that same season.
After being shown the door, Keenan would later land in Boston and fail for a season, move to Florida and fail for three more (and traded a certain goalie for a certain Vancouver winger) and finally ended up in Calgary where he did better, but still failed. These days he - like pal Mark Messier - can be seen hanging around MSG clinging to his last vestiges of relevancy.
You can't ask for a much better Friday the 13th moment than that.
