The Italian is an interesting case. I'd be curious to see effort here. My hunch is that the D1s sent APs, and a scholarship, and used their resources elsewhere. I suspect Fl Tech offered a start, and did as many visits as they could afford. And it was still a long shot. So effort and promises was not likely close - I suspect the D2 prioritized this guy much higher.
If any of those very high D1s had put in serious effort, they knock D2s off. This isn't a case of prestige not mattering much.
