The Chicago Blackhawks have lost just once in regulation when leading into the third period over the last two seasons.
Regrettably, that failed conversion just happened in Game 3 of their first-round series against the St. Louis Blues.
Patrik Berglund and Jaden Schwartz's goals scored a little more than eight minutes apart in the third period of Sunday's matinee sullied an incredible 70-0-4 run in games in which Chicago led after 40 minutes in the previous two seasons.
Chicago's last blown lead came at another critical juncture - Game 2 of the 2014 Western Conference final versus the Los Angeles Kings.
