It is a little surprising.
This kid is putting up a ppg+ in his d-1 season. Does anyone know how often that happens in college?
First round picks out of college are becoming more frequent but not very abundant. Here's the notable ones from the last decade.
2020 14th - Dylan Holloway 17 in 35 games = 0.49ppg
2018 4th - Brady Tkachuk 31 in 40 games = 0.78ppg
2018 7th - Quinn Hughes 29 in 37 games = 0.78ppg
2017 25th - Ryan Poehling 13 in 35 games = 0.37ppg
2016 14th - Charlie McAvoy 25 in 37 games = 0.68ppg
2016 15th - Luke Kunin 32 in 34 games = 0.94ppg
2015 2nd - Jack Eichel 71 in 40 games = 1.78ppg
2015 5th - Noah Hanifin 23 in 37 games = 0.62ppg
2015 8th - Zach Werenski 25 in 35 games = 0.71ppg
Pre 2015 there's not much notable, but I'll throw in Sheahan
2010 21st - Riley Sheahan 17 in 37 games = 0.46ppg
Obviously Eichel is in a league of his own, but at Johnson's pace he doesn't group with the rest of them either. College is harder to predict from just ppg, since size plays a bigger role there vs the CHL, and similarly in college you can't assume a projected first round pick is getting top minutes like in the CHL. Quality of competition can play a big role in college too, especially with the covid schedule.
