This process is no way perfect-- far from. These two boys should attend the callbacks and show their talents. If they make it good for them.
It is going to be unfortunate how mature adults "take apart" the kids who round out that roster.
This was poor planing by the event organizer. The current roster(Top 20)should have not been released unless it was the full 25 man roster. The organizer of this event should have thought of this more rather than promoting his event and telling everyone how many kids were there.
The callbacks should have been used for a second team if thats what is going to happen and not find the remaining 5 spots along with a second team.
The organizer not the evaluators dropped the ball.
