In the last few seasons we have brought up Helm, Abby, Ericsson, Howard, Kindl, Emmerton, and Mursak. We'll add Smith whenever the next season starts, with Nyquist, Brunner, and Tatar all likely in the competition, though they may need to wait a year.
Maybe if we'd had the 9th overall pick in one of our recent drafts we'd have someone like Couture. Tougher to find those guys at 19 or later.
