This isn’t two parties sitting down having a large back and forth, posters come in trying to offer what they perceive as fair value. I’ve watched every game Andersson’s played for years, I’m letting people know what value he provides to give them context for offers.
The Seth Jones trade is a good comp. Same age, Jones had 1 year left at 5.5, with Andersson having 2.5 years left at 4.5. Jones and the 32nd overall went for a recent 8th overall pick, the 6th overall pick, 12th overall pick, and a mid 2nd. Maybe 1-2 posters have offered anything close to that value. Jones play detoriating makes the trade look like a steal today admittedly. His ability to be extended immediately also boosted his value, but getting a top 10 RD for multiple seasons at 4.5M when the cap has never been a bigger factor I’d also a huge plus.
Just to point out that the pick that wound up at 6OA wasn't known to be a top 10 selection - the Hawks were trying to extend their Toews and Kane group with new help. That was unexpected so should be a caveat in trying to determine a comparable with Andersson.
