That said, it seems rather difficult to read what Team Finland's coaching staff wants to do. Some believe that he will not be selected due to his age. People are just hoping that he is chosen, and it appears pretty obvious that he should be on the team. Until he is guaranteed a spot, however, there will remain some uncertainty about his status with the World Championship roster.
It's not his age so much as certain raw aspects of his game - which, admittedly, rarely if ever manifest themselves outside young players (the inverse is certainly possible, a young player
without noticeable raw aspects - look at Barkov for example). Though even if they are still noticeable in Laine, they certainly aren't as pronounced as in most other players who are his peers agewise.
So in that sense one thing that should not be up for debate is whether he is a risk-reward player or not. He is. The standing question is, if the risks are deemed low enough, or the reward is high enough to ignore whatever risks involved. The consensus here seems to be "yes they are" (and I don't disagree), but we have no way of telling whether that will reflect the thoughts of the coach.
If he didn't have those raw aspects and was still shunned because of his age, then it would be age-based discrimination and thoroughly unacceptable. Now it'd just be, well, playing it safe. Perhaps excessively and at the cost of that x-factor that would help us win games.
