Anyone trying to make a direct comparison of Crosby at 17 and McDavid at 17 based on those numbers is missing a very important point. Crosby was 7 months younger in that season they are using. So if you want to claim they're the same age, you'd actually have to go back to McDavid's numbers from around April of last season. And that is completely ignoring that we're talking about only 14 games and that they were played in different junior leagues. Crosby's QMJHL has always had a reputation of being more high scoring/less defense. Crosby's 16 year old numbers (135 points in 59 games, 2.29 ppg) were miles ahead of McDavid's (99 in 56, 1.77 ppg), but again, I think it's not the most useful of comparisons.
Another thing I'm not sure about is how the talent level of the two teams matched up. Erie does have another top 5 draft prospect in Strome. After a quick look at Rimouski's roster, I don't really recognize any of Crosby's teammates. Both guys numbers show them to be assist guys, so that is definitely going to be driven by how many finishers they have around them.
edit: I hope this doesn't look like I'm trying to shoot down McDavid because I'm not. I want him on this team but I don't see the point of this comparison.
