There is isn't much logic to say some "will want Marner". Can you name a team that would be that NMC Marner would willing to be traded too, that has enough cap.
Even if he goes, the Leafs shouldn't be overpaying on those UFAs, especially with that term

What if I told you this is basically the same dcore that you have right now

We are at the point in the offseason where Leafs fans just assume basically every big free agent will sign with them lol
