I get the convenience of the lazy/partier implication. Especially as we are not privy to the level of information to warrant an informed decision. Though it bothers me when people/posts are dismissive of a kid by oversimplifying the situation. He has made his own bed but there might be a little more to it than that.
To clear the NCAA 40-60-80 rule he would need 60% of a degree completed by the end of his third year. At 120 credit hours for NU graduation that would be 72 hours. Not a giant hurdle but that is the actual number with which he is dealing.
1. All of those have to be applicable to the same major to hit the 60% mark. This can be very tricky if he ever changed majors or started very gen ed and now wants to go a major with a heavy emphasis. Something writing intensive would likely cause just as much problem as something math intensive.
2. All have to be at a grade high enough to be accepted by the transferring institution.
3. All of the courses must actually be transferable to NU. JUCOs are really good at creating "unique" courses that might not fit into the transferring schools curriculum. e.g. A California JUCO might have a 'History of the Southwest' course that Nebraska would not accept because they did not have anything that specific in the current course catalog(personal experience on this one). Usually this is mitigated by local JUCOs tailoring for local 4-year schools. There are large discrepancies from Kansas schools to NU let alone from Arizona schools to NU. I'm sure he would have registered for the semester with some heavy input from NU Admissions folks to try and alleviate this.
So if he took 12 hours a semester for three years he would be at 72 credits. If even one course did not transfer he would not be eligible even if he had a 4.0 GPA. I'm not claiming this is his exact situation but hopefully demonstrating that lack of guidance early in the process or a change of direction can screw a student athlete more than anything else. Even when they are doing everything they are asked.
