I've recently learned a lot more about summer tournaments, and it's a crazy racket. One of the things I've learned about is The Book.
To get into these events, college coaches have to buy The Book. The Book is a list of all the teams attending that tournament, their rosters, and all the pools/brackets for the tournament. It's a crappy, stapled-together stack of paper. The information in The Book is largely accurate, but riddled with mistakes. Oh, and it costs $500-$600 per copy. Coaches pay this without batting an eye because The Book is their ticket in, and they need to be at that tourney. Tournament operators will make up to $150,000 in cash from selling these books.
