The 49ers would have been winning by 9 with the safety – instead, they won by only 7.
San Francisco happened to be favored by between 7 and 8 points.
What did the safety mean for bettors?
An estimated 65% of the money bet on the game backed San Francisco; with 35% of the money backing Seattle.
Overall, it’s safe to say that Coach Harbaugh’s unconventional decision resulted in a $75 million dollar swing worldwide with the bettors overall losing that amount (due to 65% of action on 49ers) and the bookies overall winning that amount.
Here’s a more specific breakdown:
49ers -7 had money refunded (but would have won with the safety)
49ers -7.5 or -8 lost (but would have won with the safety)
Seahawks +7 had money refunded (but would have lost with the safety)
Seahawks +7.5 or +8 won (but would have lost with the safety)
