In his one season in Vancouver, Dermott only managed to skate in 11 games after suffering a concussion in training camp and a few "undisclosed" injuries. He became an unrestricted free agent this off-season and after a few weeks of fielding offers and ensuring teams he is now healthy, Dermott has officially signed a 1-year deal with Arizona, joining fellow former Leafs Alex Galchenyuk and
Alexander Kerfoot.
