Returning to Seattle of the WHL, Hickey began the season concentrating on his defensive game and proving that he can shut down the top forwards of the league. After anchoring the blueline for Team Canada during the U20 WJC, the Seattle coaches let loose the reins on Hickey and he went on a scoring tear, showing that he still had the skills to lead an offensive rush and to quarterback a power play. Hickey is one of the most well-rounded defensemen in major junior hockey. He does not have the raw skills that a Pietrangelo possesses or the bruising ability of a Bogosian. Hickey instead combines a excellent grasp of both sides of the ice. He will join the Kings minor league system at the end of the major junior hockey season and immediately be an option for the NHL roster.
