There is still prospects from the 2019, 2020, and so on drafts that will likely see games. I know its not "sexy" because these players come up at the ages of 22, 23, 24 but Soderblom is an example of letting the kids learn the game, find a niche and eventually come in and be ready. Soderblom may not be a game breaker but he should be a very useful player.
Guys like Tuomisto, Wallinder, Hanas, Buium, Mazur all still are yet to get their chance. Again none may be guys that put you over the hump but they need to replace guys like Motte, Holl, Petry, Fischer and such.. if they raise the talent level of the bottom pairings, bottom 6 guys it will only push the ceiling of the team next year and in the future. Throw in Cossa, Augustine replacing Mrazek, Talbot, Lyon... hard not see them improving. Obviously a fraction of those guys end up sticking but there is still a TBD aspect of Yzerman's early drafts because the team has not thrown kids into the fire immediately.
Also we have Brady Cleveland so.... watch out!
