If you havent heard of him you dont follow the draft/prospects that closely. He was ranked in the top 10 on Bob Mackenzies preseason ranking ahead of guys like Luke Hughes, Wallstedt and Lysell. His midseason one he had fallen to 11, but after that he had an all around dominant u18 tourney and an extremely strong playoff in the Swiss league he was playing in (7 points in 4 games). Now I doubt he goes as high as some people in here seem to think, but hes definitely a candidate for going off the board somewhere around 5th overall.
Not hearing about him is more on you than him having an exponential rise, he actually hasnt risen that much really
