Leafs were 32nd overall last year in 5v5 sv% and that points to system and goes beyond simply blaming the goalies. IMO
Yesterday a team coming out flat and unable to expose a young and weaker opponent on compete level as well as Keefe claiming the team hung Murray out to dry also points many fingers his own direction.
Leafs dmen often join the rush and ill advisedly pinch at the opposition blue-line which surrenders odd man rushes against and goals against. Cole Caulfield yesterday could have outscored the Leafs on odd man rushes alone, and was the reason Keefe claimed the Leafs hung their goalie out to dry.
So are Leafs dmen following coaches game plan instilled or are they free lancing, because if they're given the green light to attack, then you can't blame them that they're not defending properly when you push offense and then pay for that aggresive game plan defensively.
A Barry Trotz "defense first system" would be an organizational change in mindset.
