I was at the ND-MI game where they called the penalty on the crowd for being too loud lol. I had forgotten about that so thanks for the clip.
The crowd gets loud when it is a close exciting game...been at a lot of the top games at ND since '77 - loud for '77 USC, loud for '88 Miami, '88 MI, '88 Penn State, Florida State, etc. I always remember it being loud during Ara, Devine and then Holtz.
Big problem is the stupid timeout delays as they killed the crowd noise. Also, we've sucked so much since Holtz - people became trained to just take it and not be loud.
Put a good team on the field, make it a competitive game and it will get loud.
