Let's not also forget that
Auston Matthews is due to sign an extension as of July 1st and if the Leafs want the best chance of re-signing him to a long-term deal, it's best to have the GM that has a relationship with him negotiate the deal. The same can be said for
William Nylander. Additionally, Dubas deserves the opportunity to be the one to make any significant changes to the "Core 4", should he and the rest of management determine that is the best course of action.
