It really depends on the individual. Most of them regularly go to class, including the starters whose names you know. They do the typical schoolwork things. Lots of them go to parties, bars, sorority events, etc. They have non-athlete friends. If they WANT to experience the college stuff, they can; I mean, speaking of Riley, a few months ago my kid called me while on a McDonald's run with him.As someone who has a son going through the college search process in a different sport and has a good friend who is fielding legitimate D-1 offers, I honestly don't think the college experience really applies to athletes. Sure, they may have a little time to do "normal college things". But their non-class time is pretty much consumed by their sport. For example, family friends of ours have a son playing soccer for a mid-major D-1 school. He had to drop a class where he was doing well and enjoyed the class because he was going to miss too many classes due to an extended trip. The professor was simply not going to compromise on attendance standards and would drop him one letter grade for each absence above the threshold.
I get what you're saying, but I don't think Will Riley's college experience is anywhere close to Joe/Jane Q.Public who is not a D-1 student-athlete.
Of course, athletes *do* spend a lot of their waking hours in practice/training time, and the basketball and football kids in particular have money to drive fancy cars and rent very nice places pretty far off campus if they want. Even many of the freshmen who are assigned top-of-the-line university housing in a place like Bousfield have rented themselves another crib elsewhere. That "not living in the student housing" element is one of the most notable deviations from regular student life.
