There's no question the Seahawks have had a tougher schedule than the Broncos so far, hands down. There's no debating that.
Also, the Dolphins have had a tougher schedule, and they're undefeated as well. in fact, the Dolphins beat the Jaguars by a bigger margin than the Broncos, and yet...it seems Denver gets all the accolades simply because they have Manning.
I'm not saying Denver isn't a good team. But over-hyped? Yup. If it weren't for Manning, I doubt they'd be getting nearly as much media love.
