Everyone loves a good conspiracy. You can't rig football. It's way too violent and fast. There are plenty of upsets in the league that happen week to week and there are many storyline ' s over the years where the NFL could have benefited from where the opposite result happened.
Denver did it's job. It anybody followed them this season, their defense was that good since week 1 and performed like that consistently all season. They were a force on defense and it showed. Carolina, not once, played a defense like Denvers. The only team that shredded them was Pittsburgh. That's it. To any fan who follows week to week shouldn't be surprised to see Denver win it all with that suffocating #1 defense. They earned it.
