HALFTIME BETTING ANGLE #1
Bet the underdog when the favored team is favored by more points in the second half than in the game itself.
-- Comments: This angle went 8-10-3 last season. This was a huge disappointment because it seems the most logical -- yet it was the only losing angle of the Dalla Halftime Angles. Nevertheless, the angle has hit 56 percent winners over the period 1981-1998 and 2002 (I did not track 1999-2001 because I could not find the data).
-- Reasoning: This commonly occurs when the dog is blowing out the favorite, pulling off a "shocking" upset at halftime. Many bettors have a knee-jerk reaction and automatically go with the favorite in this spot to rebound big in the second half, which is a big mistake. It's also a contrarian play, since it generally goes against the public.
-- Update: I am certainly not going to dismiss this angle because of 21 trials and a losing season. So, I'll leave this up for at least another year.
HALTIME BETTING ANGLE #2
When one team is ahead at halftime by 15 or more points, bet the UNDER in the second half.
-- Comments: This angle went 25-12-1 last season -- which is about 67 percent. I love this angle. It is clearly related to the outcome of the second half and is a PROVEN winner.
-- Reasoning: This trend is even stronger when the road team is leading. What happens is, the winning team gets conservative on offense and rushes more than passes. This eats up clock time. The winning team can also bring in 5-6 defensive backs, since it knows the opponent will be passing more often. However, the opponent, which is losing badly and getting embarrassed sometimes will revert to fundamentals (i.e. "let's get one score first, then worry about playing catch up"). This happens often in games where the starting QB has gone down with an injury in the first half. Furthermore, if the winning team has the ball with under five minutes to play, they will often drive down the field and kneel at the opponent's goal line, instead of crashing in for another score. This means that anywhere from 1-5 minutes out of 30 minutes is wiped out so far as scoring chances. Finally -- in blowout games, field goals become less likely, since the losing team needs touchdowns to get back in the game. Instead of kicking a 33-yard field goal the losing team will often go for it on 4th down and goal or 4th and long. Odds are, the team usually will not convert or score. That puts the other team deep in it's own territory to start the next drive.
-- Update: This angle went 45-23 for the test period (1997 and 1998). Again, I have to rely on secondary data which is why there are gaps in the years. So, the combined record of this angle in years tested is 70-34-1. Anyway you slice it, this angle is phenomenal. It's good for about two plays a week, on average, and hits about 66 percent. I defy anyone to show me a better angle than this one.
HALFTIME BETTING ANGLE #3
When the road team is leading at halftime by 16+ points, bet the UNDER in the second-half.
-- Comments: This is an extension of the previous angle, but is even more powerful. This angle went 10-2-1 last season. Enough said. A winner. Side Note: For detractors who suggest this should be combined with the previous angle, I disagree. When this situation arises, it is so powerful that you may want to consider a two-unit wager (combining Angles #2 and #3).
-- Reasoning: This is closely related to the previous Angle (#2) But, it's even stronger. When the road team is leading at halftime by 16+ points, the UNDER occurs 60.5 percent in the second-half. OVERS occur only 34.9 percent of the time. It doesn't matter if the road team is favored or the dog. This happens for the reasons previously explained. But it's even stronger when the road team is winning big
-- Update: With last year's results, this angle is hitting 61 percent over a 20-year period.
