Doesn't he have to pick a graduate program that Louisville doesn't have?
this is what i saw, but im not an expert on the situation, as i read it i see what you mentioned, I dont know if you can have any one scenario or fit into all scenarios for it to apply personally. regardless he only blocked two school so I doubt this reasoning was due to degree of choice being different or not, its because his old db coach is there now:
Graduate Exception
The graduate exception is a version of the one-time transfer exception. It is for student-athletes who cannot use the normal one-time transfer exception because they play one of the sports that are not permitted to use the exception.
The student-athlete must have graduated with at least a bachelors degree;
The student-athlete meets the other requirements of the one-time transfer exception;
The student-athlete must have at least one season of competition left; and
The student-athletes previous school did not renew his or her athletic scholarship or offer an athletic scholarship for the following academic year.
The requirement that the scholarship be cancelled or not renewed is generally not an issue. The scholarship does not need to be cancelled before the transfer or be the reason for the transfer. Because the one-time transfer exception requires you to get a release, what will happen with your scholarship is generally just an administrative detail.
Graduate Transfer Waiver
The graduate transfer waiver is now typically used by athletes who have previous transferred once before and so cannot use the one-time transfer exception (even as a graduate student).
A letter from the previous school saying it does not object to the student-athlete being eligible;
Documentation that the student-athlete has been accepted into a specific graduate degree program;
Documentation about whether that degree program is offered by the previous school;
A student-athlete statement including the reasons for the transfer; and
A statement from the previous institution about the student-athletes status on the team.
Generally the heart of the waiver is the three middle bullets. The NCAA wants to see that the student-athlete transferred in order to continue his or her academic career by pursuing a graduate degree not offered at the previous school.
