Super Bowl 44 was generally pretty good for most books. With the public favoring the Colts and the Over, the action at most books likely had them wanting a Saints' cover and an Under, which they got.
But for a few high-volume books taking professional action, it was a different story. After hitting the Colts initially on opening, the sharp action strongly favored the Saints mid-week through game day, and there was reportedly a lot of non-sharp "whale" action looking to get down on the Saints as well. BookMaker accepted a number of big bets well above their guaranteed limit, all on the Saints, and admitted they lost on the game when the Saints got the double-digit win.
