Boston Bruins head coach Bruce Cassidy decided to split up the "perfection line" of Brad Marchand, Patrice Bergeron and David Pastrnak on January 1st, after a brief COVID-19 team hiatus.
The Bruins had one of, if not the best, lines in the NHL between the three. The change-up has been beneficial to adding much-needed secondary scoring.
Boston's record before January 1st was 14-10-2, for a points percentage of .577. Since the New Year, their record has climbed to 31-11-3 with a .722 points percentage (3rd in the NHL).
Cassidy has found a way to balance out the scoring between his top-6 forwards and, most importantly, at even strength, which is absolutely crucial come playoff time.
