It'd have to be a significant price from Philly, for that to make sense to me. Frankly, if i were Seattle and planning to build a roster to actually compete right from the hop like Vegas...i'd be penciling in both of Tarasenko and Voracek as my 1 and 2 RWs. That's two high quality wingers who can produce and more or less anchor a line. Albeit aging and on somewhat unwieldy contracts.
If Philly were to really sweeten the pot, and you're still ending up with Voracek, that's cool i guess. I'm just not sure what that'd be, to make it worthwhile. That 1st round pick seems steep, but at the same time...not having Tarasenko and Voracek both, makes Seattle a much weaker team to start with.
