Unfortunately you cannot put national sports championships on your resume.  No, because you didn’t do anything.  No, being a devoted fan and spending the majority of your waking hours blindly following the football and basketball teams does not count as working experience.  It just shows that you were an average Floridian high school student who chose one of the three major Florida public universities, and you happened to get lucky that this is the one that won some championships.  The fact that you have a tough time understanding this really shows the value of your education.  Better hope that your potential employer didn’t go to any other college in the SEC.
