So... the Cliff's Notes version is this..
In all sports except football and basketball, if you receive ANY athletic scholarship money, any academic money you get counts, unless it is based on firm criteria that is available to all students to receive and "consistent with the pattern of all such awards made by institutions"
If you are a football or basketball player, and you have a full ride academically, you will count toward the headcount limit the minute you step on the field/court in a game... if, after a year at the university, they are full time and have a 3.0 GPA, they no longer count against the headcount. Same rules apply though...The scholarship has to be "awarded independently of athletics interests and in amounts consistent with the pattern of all such awards made by the institution"
