Answer:
I am against the idea of the student-led prayer before a football game. The first adamant is a freedom of religion. The prayer isn't a religion that is yet made but a prayer made up by students. The prayer wasn't a official religion that is officially recognized before. This is considered as a public gathering or even a activity likewise. Plus this is before an football game such gathering or actions could strongly affect the football game.
(This is using the idea from the previous person, just toned it down a bit and a little more understandable for me).
