I don't know much about the demin recruiting process.
I read that AJ had a price and he set that price and all the schools courting him met the same price. He said he didn't want money to be the deciding factor and that it wasn't.
He could be lying though, idk.
I think the fact that he is currently living near Provo and playing ball here probably factored in as well.
I do think it's possible that Kevin Young is the best recruiter that BYU has ever had though.
I think there are many factors (BYU bball court is an amazing atmosphere and holds close to 20,000). He had a great time at the football and basketball games he attended in provo (crowds were chanting his name). BYU has a huge fan base that is best active on social media.
