If there ever was serious discussions of Taresenko to Philly via Seattle, and I have reason to think there wasn't, Maybe Seravalli had Seattles wish and San Filipo had Philly's wish. CF refused the #1 pick and Francis said "fine, you can pay me now or pay me later, but it will cost you that #1 pick to dump salary."
I don't think the original speculation made any sense, because if Seattle was willing to take Voracek, they didn't need Tarasenko to do it. They could have just taken him in the ED.
The way things stand, they got Dunn, who many think highly of, and maybe they actually wanted, and now can make the Flyers give them that #1 to take Voracek, or JVR in a lop sided trade for far lesser player than Tarasenko, if CF is desperate for cap compliance.
