This is on the PGF rules site:
"Once a team qualifies for the Nationals, all players on that team are frozen until August 7, 2011. Qualifying teams may add players until the roster deadline July 18, 2011. Players may be added from any team in a like or younger age group if the player to be added was not on the roster of a team that qualified for the Nationals in any age group. Invited teams may add to the roster until the roster deadline of July 18, 2011 provided the player to be added was not on the roster of a qualifying team at any time after the team qualified. Players who compete in a qualifying tournament at any age group may not be added to a team in a younger age group. Players on an invited team are unrestricted within their age group or an older age group until the July 18, 2011 roster deadline"

Do you agree Nationals here refers to PGF Nationals and has nothing to do with ASA Nationals?
Thanks,
