That's what was said about Miller originally
Chytil gets concussed if he uses a pillow that's too firm. Gotta stay in the lineup to progress your talents. I don't see that happening for Chytil given his overall lack of awareness on the ice, his injury track record, and various mystery illnesses/injuries that flare up seemingly at random that have prevented him from flying/practicing/playing. At least Miller can stay in a lineup for more than 3 weeks at a time.
