ranbarts2 - I went to school at a quality (but not powerhouse) D1 program in the late 70's. Ran 4:08 in the mile in HS so I was on scholarship. My coach did not ignore the walk-ons. Neither did I, or any other teammates who were on scholarship. (We had 4 scholarships total, if that). We needed the walk-ons. Plus, the school was very competitive academically, and the academic prowess of the walk-ons (who did not get a big thumb on the scale in admissions) helped our team and guys like me in focusing on school and in maturing. One of the reasons walk-ons get ignored today is Title IX. Male distance runners are a killer from a Title IX perspective - they are three-fers - and count in three sports, XC, indoor and outdoor. So unlike the baseball or soccer player, the school now has to fund and recruit two additional female athletes on one team or another for every male long distance they keep on a team. Even at a wealthy athletic school like Michigan, it has an impact. Look, I think it wrong to ignore walk-ons (I am forever reminded that Doug Padilla was a 9:17 high school two miler and many average high school runners can really develop), but the system compels coaches to be budgeteers and political animals with the administration just to keep their jobs and the program going. Walk-ons would be well advised as to understand the dynamics at play.
By the way, I regret not looking into Division III at a Williams or Amherst or Haverford. I academically was qualified, and really would have enjoyed the environment at DIII, and would have been able to focus on academics with far more intensity than I did. Loans and financial aid would have been a bit of a rough spot compared to the athletic scholarship route, but on an inflation adjusted basis college cost in the 70's 1/4 to 1/3 what it does today. It was doable. The point here is that athletes ought to be really mature in their decisions, and refrain from looking reflexively at big DI programs. And if at a big D1 program, well (just as ranbarts2 did), you will be at a big school with lots of resources. Take advantage of the once in a lifetime opportunity to grab the most resources and education that you can drag out the places - that kind of thing will not likely be offered again.
