good question, you might get a different definition depending on who you talked to. Not sure I would describe the following a helicopter parent, but it sure spoke volumes.
We were doing an event and watched one of the top players enter the park with his parents. He was a catcher and his dad was carrying one bag along with dragging a cooler. His mom sort of struggling carrying a big bag with his catchers equipment. The player was walking in front of them with his earphones on and carrying nothing. During the games and workout he would wiggle his finger to his parents and they would run down and give him something to drink.
he was one of the most talented kids at that event, but I would not have been interested in recruiting him based on watching him enter the park. He did end up with a great scholarship in a national power program. He only lasted one year there before we completely lost track of him.
