Not really with the cap going up and they have Cowan, Minten, Knies coming up, they can add some offence when Tavares is gone, I think the Leafs problem is outside of the Core 3, and Reilly, they haven't really developed or made any decent trades to improve the team.
Knies already on the roster, I think the issue is the Toronto hockey media is just a bunch of idiots who don't know shit, and the fans buy into the false narrative they have created instead of focusing on the real issue IE players development//pro scouting and providing the right supporting cast around those players. Leafs management just lacks the creativity for the cap era, look at Florida, Tampa, Vegas, Chicago, they've all found ways to be contenders in some way or another.
