But amidst all the positives that the Maple Leafs can use not only next season but thereafter there lies one big glaring negative: Mitch Marner's potential extension.
Mirtle broke down why Marner's deal could give the Maple Leafs trouble if they decide to go all-in and re-sign him:
"It feels a lock that he could command more than $13 million on the open market given how many teams will be swimming in cap space, but how much more?
Because if you go much higher than that, the $31 million in cap space the Leafs have for next season disappears very quickly. To the point that they won't be able to take advantage of the cap jump in free agency at all this summer.
Which isn't ideal, given they continue to have needs at center and on defense."
If Toronto were to re-sign Marner at $13.5M (a tough ask given that it would exceed the supposed internal cap on Auston Matthews) it would only give them roughly $8M to work with in order to fill in a ton of holes.
Marner has been lights out again this season, and has often been the team's biggest bright spot; making walking away even tougher.
He has 15 goals and 53 assists in 51 games for the Leafs and is one of only four players to play in every game this season for the team.
Even with Tavares and Knies signed, it gives them only $5M to work with to fill a third line center role, and most of their bottom line (although they may re-sign Steven Lorentz to fill one of those gaps as well).
The team needs to cut Ryan Reaves, they need to hope Calle Jarnkrok can come back and be a solid contributor but he costs $2.1M which could be spent elsewhere.
There's going to be tons of other teams throwing Brinks Trucks worth of money at Marner come July 1.
While he's been undoubtedly a huge reason for Toronto's regular season success, if the team can't get it done with him, they should look to add enough pieces to do it without him.
