What does Ivy Plus mean? I'm fascinated.
If a student is that torn between a civilian college and a SA, the SA is very much unbothered by their decision to go elsewhere. Adjustment to recruit those students is unnecessary.
Recruitment for officers needs to be a bit more deliberate than just picking up the students with the best college applications. I've worked with plenty of Ivy league, Stanford, MIT, whatever graduates. They're not special; they're not better. If you want a more recent assessment, there it is.
If a student doesn't want to go to USNA and can't give up their once-in-a-lifetime shot at Harvard, then fine. The Navy is not missing out on recruiting the "best" officers by letting them go.
