Leafs record Since 2016-17
365-193-76 (.636 Pts %)
Without Matthews 38-19-2 (.661 %) - multiple short stretches rather than many long ones. Not really indicative of anything other than the team being able to go into "weather the storm" mode for a week or so at a time.
Without Marner 20-17-5 (.536 %) - substantially worse than their overall record - 88 pt pace compared to 104.
Without Nylander 25-10-2 (.703 %) - almost entirely from his hold out in 18-19.
Without Tavares 11-2-2 (.800%) - also mostly from really short stretches.
Without Rielly 41-17-5 (.690 %) - some extended stretches, a suspension, and other short stretches.
The team has shown an ability to come together for short stretches when missing a key forward, but, in more recent years, when one of them was out longer-term (so, really, only the Marner injury), they struggle. What we're seeing are some small sample sizes, which means you can't really draw much conclusions from them. You also shouldn't be adjusting your strategies or lineup configurations significantly because of how things played out during those stretches, either. The most we can really glean from this is that we don't have to be too concerned about minor injuries to the star players. Anything more than that is a risky proposition.
