Most tournaments these days are called "Showcases" and all the college coaches go to all the showcases.
A "showcase" means three things to me - 1) the tournament fees will be 2-3X a typical tournament, 2) some college coaches will be there, and 3) it will be a friendly format with no elimination bracket. And if it is a popular showcase, you had better have some SERIOUS connections if you want to get in.
