I think Nebraska fans are a little overdramatic about our stadium not being loud enough. It gets just as loud as any other stadium (save a very small number) when games are on the line or we are playing against highly ranked teams.
We have been beating up on people for so many years that we never had to be super loud, but think about how loud it was for '06 Texas, the beginning of '07 USC, '01 Oklahoma, '08 Virginia Tech, etc. Do you really think other stadiums are THAT loud for every single game, including the cupcakes? I don't know for sure but my guess is no.
