Look at who was in front of him. The list is dominated by Kane and Tavares linemates. Two guys who went 1OA in their respective drafts. And, you were the one saying Tavares would have been thought of as the next one if he continued improving from that season. I'm saying even after that Stamkos was viewed as ahead by a decent amount of scouts. And, I believe Bedard is 6th in points per game of players who have played over 20 games. And, Stamkos was 5th in points per game at 17 while second in the OHL in goals. But, don't let facts get in your way.
Subjective interpretations of stats are not facts. But don't let that
fact get in your way.
If you remove Kane and Tavares' teammates from the list, there are still players from six other teams that had higher PPGs than Stamkos. If you are arguing that Stamkos' 16 year old season is statistically on par with Bedard's and McDavid's once you dig deeper, there is no argument that Stamkos' 17 year old season was clearly below McDavid's 17 year old season and he did not separate himself from a number of #1 picks before and after him offensively. He was arguably a better than average #1 pick/prospect of his era but not close to "generational" if Lindros, Ovechkin, Crosby, and McDavid set the bar for that label.
Similar to McDavid, Bedard played as a 15 year old in the CHL, has a notable U18 performance as the the youngest member of Team Canada (the whole tournament?), and is scaring the PPG leaders at age 16 in his CHL season. It is clear he closer to McDavid statistically than to Stamkos.
He also is 1/2 year younger than Stamkos and McDavid, and perhaps younger than that physically.
