This "it's time to move on" should be said to a number of players.
Their Defense being re-signed should be priority number one. Then trying to move Marner and/or JT. I'd also try to move Reilly. Time to take the kid gloves off and the rose colored glasses.
Time to shake this dust off this core. Bring in the same types, don't deviate from the playoff blueprint.
I saw how Vegas built their team. The Leafs just need to proper power forward. Assume McMann is healthy next year, Knies is a year older. Pick up similar types such as Bert and Domi who get in the blue paint, cause havok, play North/South.
Marner should be gone even if it means putting him on waivers or letting him walk. JT fullfilled his contract, he has a year max left.
