Quinn is speaking to the media in an hour or so, so we should find out what the lineup changes are. Nothing has been confirmed yet, and I don't remember seeing anyone report on practice lines.
One random guess is that he could try Blackwell or PDG at the 2RW spot to try to re-create the Panarin-Strome-Fast line from last year (bad idea since it's probably unrepeatable). I'd probably try this to spread out the depth a bit:
Kreider-Zibanejad-Kakko
Panarin-Strome-Buchnevich
Lafreniere-Howden-PDG
Lemieux-Rooney-Blackwell
