No, it is you who is entirely wrong and can only find inferential evidence and your own BS to support yourself.
The rules did change between 2006 and 2017, hence, that Georgia file you found was an archive. You must have missed how different the rules in that Georgia file and the MSU file were; the MSU document was much more complex. Nonetheless, neither of them mention having to be enrolled in 12 credits; you made that part up. Still, I know this about Kentucky fans: they don't let the truth get in the way.
Nevertheless, take a look at this definition of the academic year from another D1 school.
http://www.memphis.edu/registrar/calendars/academic/ay1718.php. UK's registrar page did not have a definition of the academic year, but it did identify Summer Terms.
http://www.uky.edu/registrar/content/academic-calendar. If you click on the link for the 2017-18 academic year, it lists four terms, Fall, Winter Intersession, Spring, and Summer.
A "regular" year starts in January and ends in December. An Academic year starts at the beginning of the Fall Term and ends and the end of the Summer Terms. In other words:
ACADEMIC YEAR INCLUDES SUMMER SCHOOL
Plus, a rule change in 2012 allowed coaches to work with athletes over the summer if they were enrolled in Summer School. It turns out many of the players were in Summer School already, and basketball coaches were happy that they could work with their players during the Summer.
One last thing that will show you how wrong you are. Here is a story about UK Men's basketball GPA from last year.
http://www.kentucky.com/sports/college/kentucky-sports/uk-basketball-men/article122469449.html That 3.0 average you cited earlier is true as a composite for all student athletes at UK. Plus things did not get much better in the spring
http://www.ukathletics.com/news/2017/5/11/5914618be4b06905f4f3c5ac_131467770236728699.aspx
If you click on the link for "team grades by sport" you will see that, again, football and men's basketball did not reach the 3.0 at the end of the spring term.
So, to wrap up, given that you don't really look closely at facts,
for college basketball players:
- Requirement to complete 6 credits in a semester in order to be eligible for the next semester.
- Freshmen eligibility to play in the fall semester depends on performance in high school
- No requirement to enroll in 12 per semester (This did not appear in anything you cited)
- Grades from summer school are included in their progress towards graduation;
- So, minimum requirements to stay academically eligible for the following semester: 6 credits per semester will make you eligible for the next semester. And 18 for the entire ACADEMIC year to play in the next academic year.
- Classes taken in Summer School count for your 18 credits in the entire academic year.
- Schools and conferences are free to add additional requirements if they wish.
- If you will leave for the NBA, you can do 6 credits per semester, and forget about Summer School because you aren't coming back for the following year. But you kept yourself eligible for the basketball season.
- Going to Summer School can be good for your game because the coach can work with you during the summer.
So, you will obviously reply with more BS, and I will have to point out these same things again to show that you have only brought up more BS. I can keep this going if you really want to. It will still lead to the same conclusion about my initial point: Do the minimum required to keep them eligible and pamper them at the Coal Lodge.
Lastly, there is no need for an onslaught of support. I can argue this with you with my metaphorical hand tied behind my back, especially when you bring up those links that contradict your own points.
