Generally speaking, at most programs that aren't qualifying for D1 nationals (i.e. most of the Ivies, not Harvard or Princeton), a 4:25 as a junior with strong academics can get a coach to give you a nod with admissions, especially if you apply early. I think there are multiple discussions going on here. One is what do you need to run to get a little help with admissions. You pretty much need to be academically competitive and be able to convince the coach you could be a conference scorer by Junior year. A 4:25 guy as a junior who loves the sport and is a good kid can easily convince most coaches they have a lot of upside. There is little downside for a coach to help on the margins. Remember, though there are maybe a lot of sub 4:25 juniors, not all of them can afford an ivy, want to go to an ivy, have the grades for an ivy. So that brings the pool way down. If the question is what will it take to be actively recruited or get scholarship money, that is a whole different set of standards.
