Mr. G runs a good business and my family has benefited from his often freely-given, generous expertise. However, I do think it's worth asking "who benefits from" this business model of the "three-year interview."
One answer to that question is companies like SFA. The longer, the more complex, and the more international the process is, the greater the likelihood is that his services will be needed. So they help perpetuate the notion that recruiting "must be" like a three-year job search, in fact leading every interview they post on TRN with a version of that question.
BTW, that link to the article on the similar operation run in the UK by Sarah Borwell is good reading. American players and their parents should know that they are competing for scholarships with players -- and, essentially, their agents -- across the world.
Whether or not that's a good thing.
