I respectfully disagree with this, I understand the point and sentiment. This kid is tremendously talented at playing football, so much so that this skill has the ability to make him millions of dollars. This path would make his life better than any reading could do. There are people who have done nothing but study, earn doctorate degrees and wont earn in a lifetime what he could earn in a year. If he learns basic skills (which everyone should know), he would wind up being a lifetime low level employee, and these skills could be learned at anytime.
You could make the argument to separate sports from education completely and let him try to go straight to the pros. However, if giving the young man the best chance of a good life is the objective, let him get trained by high level coaches and go make his money playing professional football. Reading can wait in this case.
