Both have showed that they are ridiculously overrated. McDavid probably the most overrated talent ever, cant even stand out when he competes against players in his own age in his home country, and he should be the biggest talent this generation? Yeah right, they are probably more than 10 bigger talents in just this tournaments.
With that said, they are both good talent, but consider the hype they have failed completely. Both will probably have a good NHL career, but that is because NHL is corrupt and always make sure that the superhype talents succeed, NHL is just about politics and for show.
Mcdavid is 17 playing against the best 19 year olds. He is 2 years younger then most of his team.
What undrafted players have looked better then mcdavid or eichel.
