If it looks unremarkable, it’s because it is. Over the course of Matthews’ career in Toronto, the Maple Leafs are just one goal better than their opponents with him on the ice in the playoffs. That’s still markedly better than the -11 differential the team sees without Matthews, but I think this is the best (and simplest) explanation as to why the Maple Leafs continue to run into walls when it matters most.
When their best player (and best units, by and large) are on the ice against tougher competition, the Leafs can compete, but usually towards break-even. When that group comes off, Toronto is a net-negative team.
Laying significant blame at the feet of Matthews for Toronto’s postseason undoing doesn’t feel appropriate, but it also seems too kind to be dismissive of it as an issue. And when you are soon to make $13.2 million per year in the seasons ahead, waiving away the lack of impact in the postseason just isn’t going to fly.
