Sounds like Friedmans chasing page hits.
What do the leafs have left to offer?
Objectively: Robertson, Liljegren, 2022 1st Round Pick, 2023 1st Round Pick (or other 2023 picks), Dermott, some lesser prospects, maybe Holl, maybe Niemla or Knies. Obviously not all of these pieces, but some. Amirov will not be traded given his health situation.
The Leafs no longer need to send Ritchie, and likely no longer need to send any salary assuming Miller comes with some retention, if they believe Muzzin will be out until the playoffs.
They will still need retention on Miller to make it happen, as otherwise they'd be in a position where they have to flip him in the offseason. Muzzin's LTIR could provide for Miller and a defensive upgrade.
