IMO this doesn't get Marner. I know it's a big package but when you dissect it, Backlund and Dube are mediocre and not needed by the Leafs, Mangiapane is the Marner replacement, and then it's two very solid prospects and two 1sts.

At the end of the day, it doesn't make the Leafs better. They aren't rebuilding, and if they do trade Marner, it would be lateral for pieces they could use right now like Rasmus Andersson or Noah Hanifin.

Why would Toronto do this? They are wanting to win now and this makes them worse.
I think If marner goes it would need to be for a different look. Maybe an Andersson, Hanifin, or Weegar package?
