Harv,
In case you havent seen this:
USA Baseball 16UBoth scouts and colleges will be at the tournament lookng for future players, so there is value beyond being considered for the National team. But each site will have perhaps 1300 players, so obviously most of them won't be looked at. It is probably the best collection of teams at this age group, and the top teams are very good, but each year some of the best players choose to not attend. For example, East Cobb discourages participation.
The teams must have 8 players who are age eligible for international competition, so teams who are trying to win may bring some players who are already 17 (but still baseball 16). The West has extrememly hot weather, while the East will likely be troubled by rain.
