That sounds more like a score the Broncos would win by. I can't see how Seattle could score 31.
I'm gonna run a prop bet competition for the fun of it. 15 "bets" of equal value. No pushes allowed. Most correct wins the normal Endzone prize - nothing.
1. Coin flip - Heads or Tails?
2. Winner - Seahawks or Broncos?
3. Peyton Manning passing yards (over/under) - 290.5 yards
4. Marshawn Lynch rushing yards (over/under) - 90.5 yards
5. Total sacks by the Seahawks (over/under) - 2.5 sacks
6. Russell Wilson passing yards (over/under) - 210.5 yards
7. Knowshon Moreno rushing yards (over/under) - 59.5 yards
8. Will there be a score in the first 6.5 minutes of the game?
9. Jersey number of the first player to score a TD (over/under) - 79.5
10. Will any member of the Red Hot Chili Peppers be shirtless during their performance?
11. Longest TD of the game (over/under) - 44.5 yards
12. Will Denver score a rushing TD?
13. Will there be a missed FG by either team?
14. Total rushing yards by Russell Wilson (over/under) - 33.5 yards
15. Total receiving yards by Wes Welker (over/under) - 55.5 yards
Good luck. tl;dr
