I highly doubt the Flyers are currently looking to trade him, but it would be something to look at closer to the deadline if they struggle again.
They have 4 NHL-level defensemen over the age of 25 - Sanheim, Seeler (extended him for 4 more years during the season), Ristolainen, and Erik Johnson (vibes/veteran leader guy on a 1 year deal). Everyone else in their system is 24 and under and prospects playing in the AHL/junior.
I think they'll try to trade Risto before Sanheim, for obvious reasons. I also think they're planning on being fairly bad this year, they've got 6 picks in the first 2 rounds of the 2025 draft and Briere has pretty much said that they think this upcoming draft is much stronger than the 2024 draft.
Briere seems to value holding onto his older core guys unless he's offered an overpayment. Rumour is that he turned down a 1st for Laughton last offseason.
My feeling is that we'd have to offer a lot to get a guy like Sanheim. Only way I can maybe see him requesting or approving a trade is if Konecny ends up getting traded instead of extended.
If we're going to use assets to get a defenseman I don't think there's a better target than Andersson.
Flames and Flyers aren't in entirely dissimilar situations at the moment actually. I think we'd have more leverage with Conroy if Andersson requested a trade and had a longer no trade list, I believe he only has a 6 team NTC. If only he wasn't on a division rival, lol
