If what you say is true, I don't think that in my most recent draft, we would have had 30/48 draftees who were 18.
You were just talking about randomness and outliers. In my current Utopia draft the distribution is 18/30 in favor of 19 y.o.
Anyways, the ratio is probably not as high as 2:1. Might be 3:2 or 8:5, dunno. But I'm quite convinced that 19 y.o. are more on average. Guess we should wait for Justin again.
