As a fan of neither team, I'd like to offer the following:
I love the Pens with Kane. That's a good fit.
But the problem is that there are WAY too many pending UFA 1-way 20-30 goal wingers that will be available this year. The price you are paying for Kane will never happen. EDIT: KANE WILL BE MUCH CHEAPER.
Because any GM can look at a 1st + prospect + more request for Kane then just go to McPhee for any of 3 options (Perron, *Neal, Marchessault), Toronto for *JVR, or NYR for Rick Nash. Note that the two players with the * are categorically better than Evander Kane and will be the ones who get the higher offers. And there are only so many buyers who will drop 1sts this year - so they can't all be worth that plus. Additionally a number of 2 year UFAs like Detroit's Nyquist, Habs Pacioretty, SJS Pavelski on terrible teams may be made available. Yes Habs fans, your team is terrible.
Due to the expansion draft, this is like the worst year ever to try and sell a young 1-way winger who isn't....like an All Star.
Buffalo isn't getting a 1st + much for Kane, they'll be lucky to score the late first and B prospect due to supply and demand, so you may get a bargain if you are a Penguins fan.
I would predict Kane moves for a no more than a late 1st and a B prospect, or more if there is a salary dump coming back.
