You're assuming that the Flyers view Garland as positive value though, I'm not so sure.
1st is likely to be middling, ideally late. But yeah, it's a 1st. I question the trade value of Podz tbh, he's young enough to still develop into something nice and there's something to be said about being patient with young players, but he really hasn't shown much thus far at the NHL level. His AHL numbers have been better this season, but overall I dunno. I think Philly would be asking for a better prospect, or more in general. Sanheim isn't going to come cheap, he's on pace for career season.
I'm also not convinced that he's available, or that he'd even want to come here given his full NTC. This is the first season of his extension, one has to assume he was okay chilling in Philly as they turned things over.
I'm pretty sure we'd have to pay for the favour of dumping Beau.
I think it'd take more, Laughton has a 3M cap hit and put up 43 points last season. 10 points in 19 games thus far so he's on pace to hit similar numbers. Maybe bump the 3rd up to a 2nd.
It doesn't sound like Philly is tearing things down, they want to solidify their young foundation. Sounds like more of a competitive retool, I don't think their better pieces are going to come cheap at all. They're also in the mix for a playoff spot at this point.
Philly being open for business sounds like "make us an offer but be prepared to pay".
