Would this not be cool to chant and change we to Coogs?
I dig it.
No, somebody tried to copyright. Here is the history: https://en.wikipedia.org/wiki/I_believe_that_we_will_win!
Personally, I hate this chant. It got very annoying during the World Cup and was something ESPN pushed on fans over and over until it picked up steam.
It's not copyrighted -- a lot of teams, including our student section at basketball games, have used it. It'd be weird hearing it at a Football game, though. And changing "we" to "Coogs" is super unnecessary.
