Loudest I’ve been are the 2008 Colorado with Henry kick and Suh Int return & 2010 Missouri. Funny thing is Colorado was bad that year and it shouldn’t of even been a close game. Honorable mention is 2010 Missouri with the Helu runs in the first quarter, the whole stadium did not sit down for that entire first quarter, also had a crazy goal line stand towards the end where Missouri got a false start on 4th down from the crowd noise and had to settle for a fg. Also the game T-Magic got hurt and was never able to get back to his full speed afterwards.
