Look at where his team placed and beside the one guy with 78 points the rest of his team has like 40 points.
Reinhart would still have be a top 5 talent in last year draft and probably would have been drafted ahead of Lindholm.
Being older can be a advantage or a disadvantage, it depends on how you look at it. Mantha is a year older (94 in a 95 draft class) same as Shrinkruak and that didn't effect there development. Actually in Manthas case it probably helped him. Finally Eichel (is a late 95 birthday) so does that mean he has less potential than Mcdavid? You forget that these kids have been playing with kids a year younger for their whole hockey career and it really doesn't matter.
