Ya, but it's a family owned business - so it'd be about the brothers/fathers interests as well.
Not always. There are many reasons why you can't/won't sell high, esp when their are multiple parties involved (like with Aquilinis).
Not sure how much GPG, PP% etc have to do with the franchise valuation. Wasn't this franchise ranked #5 but Forbes as most financially successful NHL team this yr? I'd say that's selling high.
