In season coaching changes. Part of NHL history, each situation with unique circumstances and results. The last one that almost produced the desired short-term effects happened in Philadelphia during the 209-10 season when Peter Laviolette took over about 1/3 of the way into the season and the Flyers went to the SC finals. This year the Flyers did not do as well. Examples of successful in season coaching changes would have to include Larry Robinson taking over in New Jersey with under 10 games to go in the 1999-00 season and leading the Devils to the 2000 Stanley Cup. Unsuccessfully changes are commonplace. A historic overview looking at teams, reasons and results should be interesting.
