I think it'll be close at the half with the. Broncos by 4 and in the 3rd should score early then hold off a late surge by Seattle; sounds cliche and is but by the end of the game.....
.........Broncos 30 Seahawks 20
This is with minimal mistakes and a bad int or fumble at key times even just one time could sway things real quickly since momentum will be huge in this game.
One thing is for sure is fans need to absorb and enjoy the buildup to the big game when their teams are in it since these moments can be far and inbetween. The Broncos went to 5 SBs in 13 years and it took them 15 to get back and if you lose odds are you won't be back next year as that hasn't happened in 18 years. Enjoy the game.
