I can't comment on the team, but I feel we should go all in this year. A weak division and injuries to a lot of key rivals mean we could (could) push deep into the playoffs.
As for position, I think Gaudette being used as a top six winger, alongside Horvat or Pettersson, would be a sound move. Pageau would/could be set with Roussel and Virtanen, or Boeser and Gaudette or Sutter, and give some defensive accumen to a depth scoring line, or some offense to our shutdown line.
I'd be open to Juolevi, but he and a second round pick would be a big ask for Pageau. He's finally got a pro season that hasnt ended in December due to injury and is showing promise to...well not live up to his draft position, but to contribute. Would there be any other rentals or pieces that Ottawa fans like yourself would feel comfortable with including for Juolevi and our 2nd(presumably+)? Nothing huge, but cheap contract for an out of favour player, or something to fill our depth a little.
As for salary, I was thinking more of Schaller as a cap dump, or Stecher as a piece of the return. Simply to balance our cap. Schaller is on expiring contracts, and Stecher is an RFA, if the Sens are looking for a short term, cost controlled RHD. I wouldn't presume to rehash Eriksson to Ottawa in a rental thread.
