Laine - Monahan - Johnson
Gaudreau - Fantilli - Chinakhov
Jenner/Voronkov - Marchenko
Fantilli line gets as much easy offensive minutes as possible.
I don't wanna put too much effort into it since things with Laine are so unclear, this is based on the assumption that he'll start the season with the Jackets and is ready to go, but will get traded at some point - in other words both parties still feeling like it's best to move on, but no immeadiate urgency with the situation. I'd like to see him with Monahan. Right at this moment I'm feeling a bit impatient with Johnson, so I'd like to see him leaned on a bit, maybe not the wisest thing to do but hey I don't make the calls so I get to cater to my whims of the moment.
I think they should ice the best possible line up they can both 5v5 and on the PP, Laine will be gone by TDL at the latest, so he's not gonna block a youngster for long - or if somehow the situation has changed, then at his age he's a potential core piece to go with the young talent, I'm not closing any doors with the knowledge I have, though that seems unlikely. To paraphrase I think best development for the young players right now would be to win some games, no matter what role they win them in.
If Laine & Monahan don't look good together early on, no reason to be too patient with it, just swap Laine with Marchenko to put him with Jenner, or do a JG/Laine swap, Laine-Fantilli-Chinakhov could be insane with spoon fed offensive minutes. Or just go full blender mode and end up with the lines
@majormajor proposed above, I liked those.
I don't think they should particularly cater to Laine, if he's good to go then he doesn't need that, and his trade value would rebound - if he's still feeling a bit iffy, either in general or specifically because of bad memories associated with Columbus, then it's best for everyone to part ways ASAP because nothing good will come of a "reunion" in that case.
