Playing in 40 games as a freshman at the University of Denver, Ruegsegger scored 15 goals and added 19 assists for 34 points, playing on a young team. He finished fourth in team scoring and was third in goals. He will likely spend four full years in Colorado, desperately trying to add strength and improve his skating. His skating is becoming less of a hindrance as he translates his terrific hockey sense and playmaking ability to each level.
