I was answering your assumption. It is subjective and depending on how a club view a player, and what other needs other departments have will determine if they use a spot or 4.
They actually have some very good players on occasion. They play in competition below professional academies, however they also play many friendlies against Cat 1 academies.
They have a much broader scope to recruit foreign footballers, as they are an education provider, rather than a professional football club, so different rules. This can be used by those who want to become a professional (especially in England) as a way to showcase yourself and get noticed.
