If Ottawa really wants to shake things up Buch could add a veteran star.

I think the Blues would be all over Tkachuk if he becomes available.

It's reported by Frank Seravalli https://www.dailyfaceoff.com/news/daily-faceoffs-2023-24-nhl-trade-targets:
Kevin Hayes could have good value if the Blues retain 50%

I don't think Kakko is a part of the Rangers future especially with other prospects ready to graduate from their farm system. This deal also saves them a little bit of money which would help their cap situation at the TDL.

Just a thought. Maybe an overpay but still I can't imagine Kakko has very high value right now.

Blues get younger and faster. Columbus gets more veteran experience for their rebuild and a familiar face in Saad.

A swap of struggling pending UFA?

I'm not sure the value of Faulk but I think the emergence of Kessel has made Faulk expendable.

Buffalo seems like a good fit for him as they really need a veteran top 4 defender and Faulk could play with Power and form a dominant top 4 for Buffalo.

Buffalo has the prospects and picks to give so this trade doesn't hurt them in that sense. I know fans won't be happy about Ostlund being in the deal but in all seriousness does he have a spot at center for Buffalo in the future? Or even at wing with their insanely deep prospect pool?

Anywhere. Scandella has been playing good this year and would look nice in any contending teams bottom 4.
