I would guess that this is the business model that most, if not all football, baseball, wrestling etc academies operate. These academies have to enroll high profile athletes on scholarship, not because they want to, after all these are for profit businesses, but in order to attract sufficient paying enrollees to make the business profitable. This does not mean that the paying enrollees won't get better at their chosen sport by attending one of these academies, what it does mean is that attending one of these academies does not guarantee you a D-1 scholarship.
In IMG's case they operate summer camps which I would guess are highly profitable at approximately $1,700.00 per week.So if you can't send your kid to the $60 K plus Academy you can send him to IMG for a week. An alternative to IMG is sending a kid to a D-1 college camp at a reduced cost. For instance Notre Dame runs a 3 day camp with exposure to FCS and D-2 and 3 coaches for $525.00.
