My son plays on a top travel team in TX. We have played many PG events and have advanced out of pool play almost every event.
Whether we are in GA or FL we are followed by the TX college coaches the heaviest and the other coaches present are generally there to see one of our specific players. They don't often just show up they generally are deliberate in who they see.
Point is IMO the average player needs to set the stage so to speak. Give them a reason to show up and communicate your schedule. From what I have seen with my son's teammates this is especially true for position players. Going to any event to be "discovered" is oftentimes unfruitful.
