It's because of how he fits within the organization.
The Leafs are going to be desparate for cheap players next year, and are probably not going to be cup contenders.
Fast forward to 2025-26; take a centre depth of Auston Matthews, Fraser Minten on year 2 of his ELC, and John Tavares at a massively reduced salary, and that's certainly something that the team can build off of; especially when you factor in Marner, Nylander, Cowan & Knies and 2 years of cap increases.
This exactly.
The Leafs COULD be in a position where they don't need to add expensive free agents to fill spots up front. Matthews, Marner, Nylander and Tavares (reduced salary) being supported by Knies, Robertson, Holmberg, Cowan, and Minten (plus others) is a strong collection of forwards.
They have the same opportunity at goalie with Woll and then a couple of prospects on the Marlies and in Russia.
This is how they build a great D corps. They can sign free agents to go with Rielly, Liljegren, Benoit, Niemela, possible McCabe. They will easily have room for two top 4 dmen in free agency.
