We probably won't see him back on NA ice for the rest of his career. I really thought he could have been something back in his draft year but low effort level on-ice and a off-ice lack of motivation led to Minulin's failure to develop (at first his game stalled, then he lost confidence and he actually managed to get progressively worse in the end, something fairly few players manage) and ultimately spelled the doom of his NHL dreams.
Lesson learned, dedication is important too in prospects and even if you look to defend well, skate okay and have a pretty good toolset, without the necessary character you won't make it in unless you're amongst the o,ooooooo1% of elite talents.
