On Saturday night, the Vancouver Canucks faced off against the Maple Leafs in a game that the Canucks' head coach referred to as "his team's playoffs". The Canucks used this motivation to defeat the Maple Leafs 4-1. However, the health of Ryan O'Reilly may be a bigger concern for the Leafs.
If O'Reilly is out for an extended period of time, it may not affect their playoff position significantly, but his absence against the Lightning would be a significant loss.
