Going to a PG tournament, or any other big tournament hoping to be discovered is not a great idea. I’m not talking about the already identified top talent. I’m talking about all the rest. This includes a lot of D1 talent. About 2500-3000 players will go D1. But a lot of them will just blend in.
A player wants to go to a major PG tournament presold. The travel coach recommends the player. The college coach comes to see the recommendation. Otherwise, you’re just tossing spaghetti off the wall to see if some sticks. Your one hope as an unmarketed undiscovered, as someone else mentioned is have a teammate coaches are coming to see, perform while they’re there and draw attention.
At a PG showcase an undiscovered player might put up some metrics that draws interest.
