Seeing that they won't be able to make many moves. I think you HAVE to separate those three for a few reasons. If Panarin want's big money then he needs to prove he can be a player that makes others better rather than getting the benefit of playing with the Hart winner. It would also make it harder to reach that bonus again. I'd make a few small tweaks, but it probably won't matter because Q rolls lines soo much. Schmaltz hasn't said whether or not he's going back to ND. So if he doesn't sign then swap him with Vinny and put Motte on the top line. Motte played great @ worlds and blocked a lot of shots. Q loves that. I'd swap Kempny and Gus, but if they didn't work out I'd swap them right back. I'm hoping Shaw could get more than a 5th even with Bickell's contract, but maybe not.

Thanks for looking at this and not immediately crapping all over it. It's not ideal to go this route, but something similar may be necessary if this team wants to roll four lines.
I included Schmaltz because I'd hope the opportunity to play with Kane would be enough to lure him from college. If not, then the possibility you suggest could also work. Like you said, Q will probably love Motte, but I didn't want to put him on the 4th line.
I put Gus with Seabrook because of all the #fancystats analysis BlackhawksBreakdown has done about that pairing.
I'd really hope for more than a 5th too, but hopefully a 5th is the worst case scenario.

Another thing to think about is maybe keeping Vinny in the AHL to develop more and signing Panik and/or Rasmussen. They've both proven more in the NHL and if nothing else they're RFAs that may be able to bring back mid-low draft picks.

Schmaltz will be back at UND. With that said, try Teuvo between Kane and Motte and move Hartman back to RW with Panarin and Anisimov.
