^ Percent NCAA to Total Pro takes the number of pro opportunities from the “% NCAA to Major Pro” calculation and adds in some additional professional opportunities that we were able to quantify. So, for football, this calculation includes NFL, Canadian Football League and Arena League slots available to first-year professionals. For men’s basketball we accounted for NBA, NBA D-League and international opportunities. For women’s basketball, we assessed WNBA and international roster slots. See methods notes for details on these calculations. Data on full-time international professional opportunities available in baseball, men’s ice hockey and men’s soccer were not analyzed here.
