You’re right, probably talking more about potential. Assuming being an overage who has great numbers with no talk about being drafted that there might be a gap in his game. I know being a bit undersized plays a factor. Probably could work out better for Arizona State, because he might be more likely to stick around.
The guys I thought had a bigger upside because of being young and are nice draft prospects are: Carels, Lin, Rudolph, DuPont, Villeneuve, Vanecek, Pantelas, Mackenzie, and even Klimpke, and Pickford, although I believe he has signed with Montreal. Like you, I don’t follow the OHL, but assume there are a few there as well.
No doubt Arizona State is getting a guy that could be running their power play for a while, but like I said, so many great players out there so compete level may be a determining factor who becomes a stud, and who is just a bit above average in college. Might be wishing we had a player of his caliber for longer rather than a shorter stint of a guy who takes a year or so to get up to speed, but when they do is signed by their draft team.
