How many gallons of soft drinks will be drunk at a Super Bowl?

approximately 300 gallons of beer are drank in one NFL game

I believe the above estimate is way off! Based upon figures from Invesco Field at Mile Hi, they serve 70,000 beers at any given game, or the equivalent of 700 kegs. Using my college math...a keg holds 15.5 gallons, so that is approximately 10,850 gallons.
