One of a huge top-four group of defensemen in Moose Jaw. At 6’5, played more minutes per game as the season progressed. Will have to improve foot speed. Goaltenders will love him, as he is capable of physically clearing the area in front of his own goal. The tough defender can deliver devastating body checks but still needs to improve his angling, reverse pivoting and gap control. He's starting to show some offensive upside to his game, makes a good first pass up the ice and possesses a hard, heavy shot from the point. The big blueliner could grow into a potential top-four defenseman at the NHL level.
Edmundson will play his third year for the Moose Jaw Warriors in the WHL and is expected to take on a bigger role on their defense corps. The big defender was traded to the second place, Kamloops Blazers just 29 games into the 2012-13 season.
