Well, they have to stay healthy, for one thing.
Last summer, the expectation was that Couts, Hayes, Allison, Laczynski would all play. Brassard was added when they found out Laczynski would be gone most of the season. Frost started in the AHL b/c he wasn't 100% back in camp from his shoulder injury.
This season we should get Couts, Hayes, Alllison and Laczynski back, N Cates has shown he's ready, Lindblom should be better a year away from cancer, Frost and Tippett finished the season strong, and Brink and Ratcliffe will have a shot at a job in TC. With Foerster, Desnoyers, Wisdom and Lycksell in LHV, hopefully we won't have to rely on Willman, Hodgson or Brown.
