Good decision on Kastelic. With the number of prospects and young players in the organization and the current goals of the team (development year, can't win the Cup, just making the playoffs would be quite the accomplishment), there's absolutely no need to rush any prospect. Let him go back to junior and dominate so he'll be more ready to have an impact at the AHL level next year when there's also going to be more spots open with graduations to the NHL.
Edit : it says Daccord has also been cut, is he going to the ECHL?
