I'd be curious to know how much of Axel Andersson's point production in SuperElite this past season was on the PP.
In their 16 year-old seasons in the SuperElite (2016/17), Andersson had 11 pts (3 g, 11 a) in 29 games; Ginning had 10 pts (0 g, 10 a) in 29 games.
This season (17/18), Andersson had 2 pts (1 g, 1 a) in 12 U18 international games for Sweden; Ginning had 7 pts (2 g, 5 a) in 13 U18 international games for Sweden.
Obviously, Ginning also has played 12 reg season and 2 playoff games in the SEL in 16/17, and 28 reg season and 7 playoff games in the SEL in 17/18, versus Andersson still having yet to play a game in the SEL.
I would also say that, based on the video I watched of Axel Andersson, he seemed (while skilled) to be a small PP specialist type, and the Flyers already have plenty of young PP defensemen. I'm not sure the Flyers would be the best fit to maximize his attributes.
