If you watch back all the series... you will find that Marner is behind many if not most of the backbreaking goals against. Ridiculous delay of game penalties, risky flip pass hail Mary that is intercepted, failed clears, giveaway on a attempted deke, the panther pass to matthews inside his own blueline, the Pastrnak one... I can name at least 7 backbreaking giveaways that led to gwg against in critical games. That's pretty incredible.
They should create a stat in his honor; GLG
