Player-wise, the only thing changing for sure is that
Mitch Marner is going to play somewhere else. He may well get himself a Stanley Cup someday, a la Phil Kessel in Pittsburgh, but it’s all too clear he can’t be a central driver of team success in the playoffs, at least not in Toronto.
Maybe in a market with less pressure, he’ll be able to go forward more, to not default to slinking laterally and flipping pucks into the neutral zone. Maybe a new situation frees him of the fear of taking chances.
But even if that happens, it won’t be on the Leafs for moving on from him, it will have been on the player. It won’t be “How did the Leafs not see this playoff success coming?” It will have been “Why couldn’t he do this when he was there?”
In that sense, it’s a pretty low-stress decision.
Yet still, they’re likely to be worse off without him, at least in the regular season. The hope is they can improve their under-pressure performances because you don’t walk through the fires of hell to win a Cup without your feet getting hot.
