Your post is very misleading. The IceDogs have four 16 year-olds and two 17 year-olds on the team. They now have another 17 year-old in Charlie Burns, who was called up from Jr. B since Vandenberg was traded. The other players you are referring to are callups, like 8th round pick Eric He, 9th round pick Darcy Dewachter and 13th round pick Rafek Dianov. It's unlikely any of them will make the team full time.
Then you go on to say that they will have 2 imports and 6-8 players coming in from the U16 draft. Every team will have imports and players coming in from the draft. Although to be fair, DD has largely ignored the import draft, selecting only one player over two import drafts. It's unlikely he would ever draft two impact imports.
My point was that this is an older IceDogs team and that they are not young at all. In 2 years time, who knows if they will be better or worse than this year as the majority of players from this year's team will no longer be playing in the OHL.
