Yeah Anaheim should be paying a mint... Vatanen is a very good player. And we're talking about a divisional rival, even if Vatanen and Silfverberg got traded and Bieksa was bought out forcing the best team in the division to dismantle would have had more value than a late 1st so the price should be high.
Too bad for Vegas they couldn't just get their hands on Vatanen though. Murray-Vatanen pairing as a starting point would have been a great young foundation. Also fill in the rest with #4 dmen from around the league and their D would already be better than the Oilers
