I think it's likely he played the moneyline on the Colts, then came back big on the Saints. The Superbowl is a game notorious for small moneylines on favorites, because people who make one bet a year love to bet the dog to win outright. I don't recall the line on the Saints in last year's game, but if they were, say, +6.5, the ML on the Colts was probably like -175. I know that sounds crazy, but this happens every year when there's a fav of 3 points or more. (Not this year, as the SB fav will probably be close to pick.)
