From kypreos' article in the star today:
But if these playoffs go south, maybe a new voice at the top would finally say enough is enough.
A domino effect of massive off-season change could follow, including moving on from Mitch Marner and finally ending the Core Four era. If anything, it would be Marner’s contract status, with one year remaining before free agency, that would dictate this decision the most. If the rumblings are true and he’s looking to surpass Nylander’s eight-year, $92-million (U.S.) deal, what other choice would the Leafs have but to trade him?
