1) I would argue that these contracts are only "franchise crippling" if it prevents us from successfully re-signing our core players (Boeser, Markstrom, Pettersson, Hughes, or any other young player on our team that promises to be an integral part of our core).
2) If you want to talk about "franchise crippling contracts," see Maple Leafs Toronto. Unlike what will likely be the case in Vancouver, the Leafs' contracts and cap structure serve as hindrances AFTER their core had been signed, post ELC's. Their core players didn't accept cap friendly bridge deals because Dubas paid a premium to Tavares beforehand.
The Canucks on the other hand, already have two extremely cap friendly deals to Miller and Boeser. They'll likely get a bridge of some kind from Hughes as well. Contracts such as Pearson, Schaller, and Sutter will all come off the books by the time we need to re-up Petey and Hughes. Baertschi, Beagle, Roussel, and Ferland will be off the books by the time we need to re-sign guys like Horvat, Boeser, and future RFA's such as Podkolzin and Hoglander.
Our only contract hindrance right now, is Eriksson, but that will likely be addressed as well.
