To be clear, I don't have any first hand, definitive knowledge.

What doesn't add up to me about your claim is:
1) Why would Neeleman care where the program was administered, if it was just going to stay a club program? In light of recent developments I'd understand (Rugby, etc), but to an outsider w/ little knowledge of the inner-workings of the Student Life admin, why would this matter?
2) Why would he offer BYU $100k over 4 years and then turn around and offer Utah millions to take the program D1? The two paths are completely different in size and intended outcome of the donation. Doesn't make sense to me that he would have gone to such a modest plan A, to such a massive plan B.
