Roope Hintz is an interesting comparison with Slaf. But it doesn't fit very well... Hintz spent two full years in Liiga after being drafted in the 2nd round of the 2015 draft, and then one year in the AHL to boot. He burst out as a solid player two years ago at age 24.
He definitely wasn't rushed but I don't feel like his relatively slow trajectory is all that encouraging as a comparison. For one, Slaf
hasn't returned to Liiga and secondly, anything could've happened between June 2015 and October 2020 (prior to his breakout PPG season) that could've derailed his career and precluded his ascendance. It's a catch-22: if the player is left to ripen it's likely going to lead to better outcomes... but it leaves him to be vulnerable to the inevitable vagaries that come with time/exposure in such a physical game with none of the reward (ie him actually getting to help the NHL team win games/series/cups).
