2. Roope Hintz
He's only 26, but Roope Hintz, the 49th overall pick in 2015, already looks like one of the biggest steals of a draft which had plenty of steals. He made his NHL debut at 22, and wasn't an immediate star (no pun intended), scoring 22 points in 58 games in 2018-19 and then 33 points in 60 games. Those are, of course, pretty good seasons, especially for a 23-year-old, but not enough to have him this high on this list.
And then... he found another level. In the last three seasons, he has 89 goals and 101 assists, for 190 points in 194 games. He scored 37 goals this year, more than Sebastian Aho (the Carolina one), John Tavares, Brock Nelson, and Steven Stamkos. In the past three years combined, he's 21st in the NHL in goals per game. He's become one of the best goalscorers in the league. And he's only 26.
