-2024 or 2025 or 2026 1st Round Pick (Conditional Protection)
-2024 4th Round Pick (Conditional, the best of Ottawa's three picks)
-Tyler Boucher (1st Round Tier Asset)
-Lassi Thomson (Throw in body, organizational depth for the Flyers)
-Mathieu Joseph (Cap Dump)
-Oliver Bonk (1st Round Tier Asset)
-Nick Seeler (Pretend he is from Carp)
-2024 5th Round Pick (Conditional, if Philadelphia acquires more than one 5th round pick, Ottawa receives the worst of the picks.)
Conditional protections on the 1st are that Ottawa can choose which pick they give up, they also receive top 10 protection on the pick if it is in 2024, or top 5 protection if the pick is in 2025, no protection if it is in 2026. Those options are needed due to how convoluted the Boston pick is and how much the value might swing depending on what happens with various teams not involved in the OTT/PHI trade.
That gives the Senators another NHL #7 type D in Seeler. Lassi goes the other way because the Flyers will need organizational depth. I doubt they would want JBD due to his contract.
We are assuming that they value Boucher more than Bonk, which may not be the case, but if it is true that they asked for Boucher or Greig, then they obviously value Boucher very highly for him to be seen as interchangeable with Greig.
The entire logic is, look if we're going to get raked over the coals, you have to give us a good story to distract from the optics of what we're doing. That story is that they bring in Oliver Bonk in exchange for a prospect who is one of the least popular prospects amongst hardcore fans, even if people in the hockey world view him much differently.
