I was shown around MSU by a Professor, who happened to be the Department Head at the time, who taught the subjects that I was majoring in. And at one point a Grad student showed me around on campus as well.
Now granted I was not an athlete, but if I had been an athlete interested in playing Football at MSU I would want to be showed around campus by a Senior player, or a Coach, or even a former player. There are more than enough pretty girls walking around campus at MSU and most other schools to stare at---side note, I'm not sure when College girls started jogging around campus in just little Nike Tempo shorts & sports bras, but it is WAY better than the oversized T-shirts and sweatpants that they jogged in back in my day! So I really don't see a need to specifically hire attractive young female students to show athletes around campus.
