Anderson is a proto-typical butterfly goalie who stays very square, tight, solidly upright and is sure of his abilities. The poised netminder has a calm demeanor, mental toughness and is quietly effective while having good rebound control and tracking the puck well in traffic. He has an added advantage by catching with his right hand and is rarely caught over-amplifying his movements or missing angles.
Anderson will be competing in his first professional season as he battles for backup duties in Worcester. He could see starts in the ECHL playing for the bulls if the Sharks would rather he gain more real game experience.
