Great spreadsheet.
I still wrestle with the academic component. For athletes its a different ballgame when compared to regular admits.
I think there are two angles within that index: (1) what does a kid need to get in as a baseball player and (2) do athletic demands cause athletes to deviate from the percentages of students in various majors as detailed in the Common Data Set (and, if so, how much).
I think a great majority of D1 schools (virtually all of the power and mid-major conferences) admit athletes who meet minimum NCAA requirements and the list could reflect that. This board could probably fill in info for all the other schools.
The second angle is harder to tease out; in going through a few random rosters at a few random schoold, I found reliable info very sparse. But, I am certain that except for a very few, most players do sacrifice either grades and/or majors. The magnitude of sacrifice is a very important variable for anyone intending to eventually enter the work force.
