This [question](https://academia.stackexchange.com/questions/131523/teaching-a-class-likely-meant-to-inflate-the-gpa-of-student-athletes) and the pertinent answers suggest that, as a rule, college athletes in the United States are not held to the same academic standards as other students. It also seems that this is well-known.

If so, employers, and especially academic employers, can be expected to discount the degrees and the GPA of college athletes in order to control for an informal "athlete's bonus", when screening applications. 

Do employers, in fact (but likely not formally), discount athlete's grades and degrees? What is the approximate discount rate (e.g. the average athlete's bonus)?
