"Campbell's high points still make the Stars believe he'll be worth the 11th overall pick, but the journey has been interesting. The lanky goalie has been sidelined most of this season by a quadriceps/knee injury, but was rock solid in five games - all wins. In a perfect world, Campbell would seize the No. 1 job and get the AHL playoff starts. With Dan Ellis under contract another year, Campbell is still a year away from becoming an NHL back-up." (Mike Heika, The Hockey News Future Watch 2014, p, 28)
