They are not getting 5,000 bucks each to attend. Igloo probably paying them 1,500 plus hotel . They will get a big turnout because some LI clubs won't be in MD for fall tourney and those schools will send asst. coaches to MD
80 kids per age x 4 ages = 320 kids 320 x $435 = $139200 15 coaches / 139200 = 9280 per coach per kid. How much do you think they are splitting that up by?
