Betting on the Super Bowl point spread is one thing, but if a bettor thinks he has really good idea of the eventual outcome, and would like to cash in at a price, he might want to take a shot at picking the exact (to a degree) margin of victory.
Super Bowl bettors have that opportunity, with some tempting prices, at sportsbooks specializing in prop bets.
Bovada, for example, is listing San Francisco as a 3.5-point favorite for Super Bowl XLVII. Accordingly, a Niners victory by between one and six points is listed as a 3/1 possibility on Bovada's "margin of victory" Super Bowl prop board.
San Francisco winning by from seven to 12 points is lined at odds of 4/1; by from 13 to 18 points is getting 6/1; by from 19 to 24 points is listed at 10/1; by from 25 to 30 points is getting 16/1; and in crazy mode the Niners winning by 31 points or more is being offered at odds of 25/1.
On the other side of this bet, with Baltimore a 3.5-point dog, a Ravens victory by between one and six points is listed as a 4/1 offering at Bovada. (Check out the full listing of margin of victory Super Bowl 2013 prop bets here.)
Baltimore winning by from seven to 12 points is listed at 6/1; by from 13 to 18 points is getting 10/1; by 19 to 24 points is getting 20/1; by from 25 to 30 points is lined at 40/1; and if the Ravens win by 31 or more points that proposition would pay out at odds of 80/1.
Last year the Giants upset the Patriots, winning Super Bowl XLVI by four points at 21-17. In doing so the G-Men hit on the "margin of victory" prop board at odds of 8/1.
Over the last nine Super Bowls, the average margin of victory has been 6.5 points, and six of the last nine Super Bowls have been decided by six points or fewer.
