Colleges won't be forced to feed money under the table to star athletes. Not only that, but coaches won't have to worry about grades and eligibility of their athletes. As for rules to keep costs down, they would almost disappear because the NCAA would not have to investigate suspicious deals between colleges and athletes. This saves millions of dollars for the NCAA, which can go to offer academic scholarships or whatever they would choose to do with the money. Athletes on the other hand, can still play a sport even if they were unable to pass the college entrance exams.
Conclusion Going to minor league teams is a win-win situation for everybody.
Athletes are able to play in a competitive environment and be paid legally and the NCAA is released from the burden of hiding scandals. Coaches can recruit athletes without worrying about losing their job because they offered an athlete a gift. Athletes can still go to class, but it would be on their own time. The minor league system has been around for a hundred years, and by the way, it's legal.
