I think the list works as it is. Let people decide for themselves if one aspect or the other is under or over-weighted and either include or dismiss schools accordingly. As far as a D1 list, all kids (and likely their parents) THINK they are pro prospects when they start, and most will probably overweight the baseball aspect in their decision process. I think some outright ignore the academics in their decisions, even if they were good HS students.
As far as adding a factor for coaching or administrative support - that would be great, but it seems pretty subjective. Who decides what good support or facilities are and ranks them? I think any list, whether it's this one or any other, points you in a direction. After that, it's up to the families to do their homework and make the best decision possible for their individual situation.
It's just a guide - and it looks like a pretty good one at that.
