When Galchenyuk played his first NHL game he was 19, not a child. Also his family was adamant he live with his parents & sister… which he did, so he was in conceivably protected surroundings in Mtl.
This didn’t start overnight after being selected by Habs..there are deeper family issues here
He was simply not serious about his career, wouldn’t be shocked to find out one day he never even wanted to be a pro hockey player but did it to please his father like Daigle and many others
- iirc he suffered a major knee injury the year he was drafted... Not sure what your experience is with elite athletes, but to recover from that kind of setback and return to an elite level requires considerable diligence in rehab. To suggest that he wasn't "serious about his career" is an exaggeration. Play hard party hard is far more common than fans appreciate.
- family isn't by default "protective". It can be as or more damaging than no family
- not interested in arguing semantics... 19 is still "teen", but regardless, physical and brain maturation is still in a rapid state of change at that age... And until 23-24-25... The impact of external influences on development are most prominent while the brains plasticity is still very active. Those influences don't stop at that age, we as human beings remain adaptable until we die, just the degree & ease of influence that changes/reduces
Bottom line... Success or failure is never just a matter of individual merit or blame. Those types of narratives have no grounding in brain & behavior science (nor the wisdom of indigenous ways of knowing).
He's the product of his unique path, one that his choices & behaviors certainly impacted, as did those of the people around him. Unfortunately for him, the professional organization that he stepped into lacked competence... A better environment may not have been enough to help him take a better path, but the toxic one he lived through certainly didn't help.
