There is no report on this, completely just my own thought, so don't take it as a rumor with any validity ...
Won't surprise me if buffalo and Seattle swap 1st and 2nd overall. Buffalo reportedly loves eklund (I can't blame them!) but at first overall you have to go with power. I think they had ideally hoped eichel would have been traded by now and they would have had an extra top pick to get him with. I doubt that happens this week. Plus the now-rumored teams involved don't have high picks (I think eichel is definitely going to Minnesota. Actually a pretty easy deal to get done imo).
On the other side, Ron Francis LOVES defencemen. Look through his GM history, he likes to build from the back-end. Matt beniers is the guy rumored to go at 2, but if Seattle stayed there i think they'd go with edvinsson or hughes (probably edvinsson). But the step up to power could be pretty big. You could possibly have a franchise dman (ekblad-like) in power if you move up one spot to a team that probably doesn't mind moving down.
Just makes too much sense to me for this not to get done. Buffalo will want to offload a bad contract and Seattle has more than enough cap space for that.
