Lias has played 9:33/game. There are 9 players classified as rookies this year who have played less than that (min 10 GP and of various prospect levels) - Gustafsson/Luoto/Chalpik/Timashov/Gregor/Beaudin/Kamenev/Poehling/Verhaege. That's 3 second rounders and one first rounder.
19 rookies played less than that last year. Notable ones being A.J. Greer, Appleton, Kamenev, Lemieux, Frederic, and then Kyrou at 9:40.
It's hardly unprecedented usage and I don't see any of the other guys quitting. Even if he was the highest draft pick there so what? His production hasn't been better than many of them.
