The multiplier that many sharp bettors rely upon is 2.3.
That means if the point spread in a game times 2.3 is greater than the betting total, we're likely in correlated-parlay territory.
For example, this week Ohio State is favored by 28 points against Marshall. The betting total is 47 points.
Bettors should play a two-leg parlay of Ohio State -28 and over 47. An equally appealing alternative would be to play Marshall +28 with under 47. (We're assuming bettors can find a book that will accept this kind of action.)
