Then what do you do in the case of someone like Hughes, who is closer in birth year, rather than draft year to Lafreniere. Or someone like Crosby and Mackinnon? Crosby was 6 weeks older, and MacKinnon was about a month. In general, people go by birth year when comparing CHL talents against each other. Still, if you want to go by draft year, I'd say Lafreniere's D-2 is still significantly less impressive than John Tavares's, and probably less impressive than Taylor Hall when you factor in how scoring translates from each league.
