An illustrated guide to firing NHL coaches during the season

As we reach the quarter pole in the 2011-12 NHL season, we've had one coaching change (Ken Hitchcock in for Davis Payne with the St. Louis Blues) and several other teams thinking about a change.

This got us thinking about how often — and when — coaches get canned in-season, and how it affects their teams. Via Puck Daddy's Master of Graphics Dan Gustafson of Sixteen Wins, here's an Illustrated Guide to NHL In-Season Coaching Changes Since 2005-06 (and through Nov. 24):

Here's the standalone image.

From Dan Gustafson, some analysis of the data:

It does, at least short-term, seem to work (bumps in Winning percentage and Points). Getting to the playoffs, however has a lesser success rate, 44%. And only one time has it worked to change coaches and win a Stanley Cup (Pittsburgh 08-09). Another odd thing is, the majority of the changes seem to be in the Eastern Conference (10 of 14 teams). And only one west coast team made a mid-season change (Kings) otherwise the furthest team west is the Blues (3 changes though!).

The success rate, one imagines, could be due to teams changing coaches after it was too late to affect their seasons. That plus-13 average point change tells us that GMs are better off pulling the trigger sooner than later in many cases.

(Dan will be working with Puck Daddy on creating some whimsical and informative NHL graphics throughout the season. If you have any requests, email us at Visit Dan at Sixteen Wins and follow him on Twitter here.)
