In order to win the teaser bet nothing more or less than an exotic parlay, the bettor must win all of the games. Any one loss negates the ticket. Many properties have canceled the two-team NFL teaser as a losing proposition for them, based on the fact that so many of the games end in a close decision.
By betting teasers on the underdog receiving more points while simultaneously taking the favorite giving fewer points on different tickets, the observant bettor has a relatively enhanced chance of winning both sides.
In college football betting, the teaser is not nearly as effective. There are many more blowouts in college, so that the favorite would not need the lowered number and the underdog will need far more help to cover than 6-10 adjusted points.
Buying The Hook
Long-time Las Vegas handicappers will tell you that the importance of getting the best number possible cannot be overrated. One of the chief advantages of living in Las Vegas is the immediate access to betting numbers in so many different books. This situation is not nearly as good as it was 10 years ago, before so many properties consolidated with the betting lines commonly shared.
But the opportunities to bet a game and get the best number possible remain. If you are visiting, you can take advantage of these opportunities. Realizing that time may be a limiting factor, you can still ask who might have the best number for your game.
According to Roxy Roxborough and Mike Rhoden, co-authors of the authoritative Sports Book Management, the most common margin of victory is 3. This number occurs approximately 16% of the time. No other result is nearly as frequent, with the next closest 7, at 7.2%.
Many properties will allow you to pay 6-5 (12-10, rather than 11-10) and "buy" the extra half-point or "hook" in either direction, to get off of these numbers. Some books have reservations about buying off of 3, but it never hurts to ask. If you believe that the game will be very close, it might be worth it to you to do this.
An example might be if you saw the New England Patriots favored by 3 over the New York Giants at Foxboro, Massachusetts. You believe the Pats can win, but are afraid of the Giants defense. You "buy the hook" and make the Patriots a 2.5 point favorite so that if they win by a field goal and the margin of victory is 3, you win. Without doing this, your bet is a push, or tie.
