Having been involved in the selection process of selecting teams for this tournament, dont think its some time consuming, calculated process, its not.
My other issues has always been its based on what you did last year. With the turnover of teams today, many teams that were great last year, may not be quite as good this year. Especially at the 16 and 18U level, where players have left many of the "established" and well known teams for Gold Teams, both here and in Chicago. Though a short resume', The Fall is all you have to base teams on for this year. I know some players couldnt play, but it is a better measure then last summer.
