So 1M overpaid ? Not a significant amount, you can live with paying your franchise player like that. I don't think $1M is going to cripple the Leafs.
In a vacuum, no, it won't. Call it an "American playing in Canada with a ton of pressure" tax.
But that's not what I'm saying.
I'm saying that in the context of how the team is currently built, having Matthews at $13.25M will make it very hard to win.
I would think differently if Marner was traded, Nylander had re-signed for less than what Marner is currently making, and then Matthews had signed this deal.
Maybe that'll still happen. We'll see.
Otherwise, the salary structure on the Leafs for the next 2 seasons is still a big problem.
