I feel Colleges would loose many things if big times sports would be lost. First with school spirit, any time before a big game all the students get together and celebrate. I feel this pulls the college or university together by having everyone in one place, everyone there has something in common. If there would be no sports I feel there would be much diversity. There is nothing that would bring students from every department and background together and have one thing in common.
Sense of community goes along with school spirit.
As I stated above, this brings everyone together from many different backgrounds to one place. This gives the students the opportunity to have something in common with the rest of their school. This also makes them feel proud of what school they choose to attend. On the other side of things, if a school would loose big time sports, their schools public relations notices would be lost. This sometimes would be a positive thing but could also be negative.
