With all the "racing" to the playoffs, if you consider the standings with each team having played the same number of games the eight playoff teams have been the same since Edmonton took over from Calgary after game 45. Interesting to note the two division leaders at that point are the two end of season wild card teams. And the two wild card teams could end up being the two division winners.
Other than a little back and forth between Edmonton and Calgary, the same eight teams have been in a playoff position since basically game 25.
American Thanksgiving was around game 20 for most teams. For the final 62 games of the season Winnipeg, Dallas, Seattle, Vegas, and LA were in a playoff spot for all 62. Colorado and Minnesota were in a playoff spot for 60, Edmonton for 56, Calgary for 8, and St Louis and Nashville for 1.
