One other question, do college coaches really want to "waist their time" going to a showcase where a good portion of the kids are already committed?
It depends. Sometimes they have know certain uncommitted kids that interest them will be at event, so they go there to see them.
Sometimes they are in the area anyways and want to see how one of more of their commits are doing.
Sometimes they just go because they feel it's worth the time to potentially see someone that interests them.
