Something I noticed that might be interesting. The Ducks drafted 8 players total. Of those 8 players, 4 were not first-time eligibles. Obviously there's Andersen, but Roy, O'Brien, and Megna were all guys who were eligible and passed over last year. And it's interesting to note that 2/3 of those are college guys (Roy, Megna), although Cooper and Kerdiles are college guys drafted at 18.
This approach does not appear to be exclusive to the Ducks. I have read a number of articles indicating that there were a larger number of non first-time eligile players taken this year. There are a number of possibilities for this. First, this was considered a weak draft, so in the later rounds the teams could have decided to take a different route and select older players. Second, one of the problems with drafting 18 year olds is that their development is not as predictable as any team would like. Some get a lot better, some get better and some just don't improve at all. By choosing an older player the teams have seen another year of development, and thus have a better idea of the eventual quality of the player. Certainly, on a more marginal player that extra year of development and evaluation can be important in the determination on whether to draft a player. Third, it was just random and the stars lined up that way.
