I think this is a good question.
APR seems to assume a set time frame. I get all warm and fuzzy about Tech athletes that come back and finish their degrees after time away pursuing professional sports careers but that does not seem to be included in the equation in any kind of meaningful way. Ultimately, I think what we want is for young people to be able to pursue their dreams in good faith and go as far as they can in a chosen endeavor. A kid who drops out but later starts over at community college and eventually ends up with a degree and a job he loves is a success story, no matter how the NCAA interprets it. Likewise, a student who realizes academics are not for him but builds a sound future through sports connections is also a success story. On the other hand a student who is just gaming the system, and keeps expecting handouts along the way, is not something that I think anyone on here would endorse. And I think we would all take an equally dim view of athletic departments who take advantage of these kids, as well as loopholes in the system, to feather their own nest.
As you say, it's complicated.
