He had the most points in the tournament for non-19 year olds. This is always said to be a 19 year old tournament, so he was the leading scorer of everyone else.
And this is the same thing he's doing at BC and did last year. No disrespect to Smith and Leonard, but he went far after them in the draft and the one of the line that is scoring the most now in three settings (NTDP, BC, U18, U20 Worlds) is Perreault. He's the best scorer of the three.
It might not translate to the NHL, but he's been a top scorer everywhere the last two years. It's hard to not get excited that we might have found an eventual replacement for Panarin (a left-handed version) at 23OA last year.
