The problem with many D1 athletes, particularly in football, is that if it weren't for their athletic talent, many of them would not be qualified for admission to the school. Many athletes have been promoted for sports from early grade school on up, with absolutely no regard to whether or not they learned the material. It's awful, really, and many of them never catch up. Being taken into an environment where they are academically over their heads is not really their fault; they have adults who should know better always telling them that it will work out fine.
My first job with LSU's athletic department was as a football tutor when I was just a freshman. I tutored English, and getting my guys through Freshman Comp was a herculean undertaking, because most of them could not read anything more difficult than Dr. Suess. They used to call me at all hours begging me to come over to Broussard Hall to read their assignments for them. (Not all athletes had personal tutors, only football and basketball players whose single-digit ACT score made it clear that they were not going to survive college classwork without help. Those sports made money for the school, and the Athletic department paid what it took to keep them academically eligible as long as they were playing. However, once they were cut or had done their 4 years, the tutoring was gone. I had guys break down in tears because they weren't drafted and suddenly realized that school was the only option left, but discovered that no one else was going to pay me for helping them anymore.)
