I know most people on here will say that showcases and camps are a waste of time, but we didn't play for a power team because my son wanted to play with friends. We used showcases and camps exclusively and it worked out well. When he committed, he was talking to or had offers from about 15 P5 schools. It just depends on the path you want to take. We knew 2 kids who didn't even play summer ball, only did showcases and both committed to P5 schools before junior year. We just did PG and PBR, and then camps for schools my son was interested in. In the end, it probably not much more expensive than playing travel ball with flights, hotels, etc.
That said, our plan was for recruiting. If you ask 15 different people what you need to work on, you will probably get 15 different answers and a kid that is in his head way too much.
