Looking at the Broncos schedule, it has to be them. The Saints have at least 3 games on their schedule they might be underdogs in.
I don't think any of them will make it, but KC has the best shot. Slight edge over DEN imo. There aren't many scenario's where the Saints beat the Seahawks in Seattle. @NYJ & @CAR will also give them trouble, though winning @CHI last week was impressive. I think Denver loses @KC. The Broncos have a very tough schedule later in the season, and their defense has been exposed. It's hard to imagine anyone beating them in a shootout, but their offense is bound to slow down somewhat. Just can't see them getting through KC, @NE, @KC, TEN, SD, @HOU without 1 loss. The Chiefs might be the most balanced team in the NFL this year. They get consistent pressure rushing 4-5, their secondary is great, and their home field advantage is top 3. Throw in the explosive run game, consistent pass attack, and they can play with anyone.
That's kind of random. Every year of his career, he has had more yards per game and more yards per carry in the 2nd half of the season than the first - sometimes by large margins. For his career, he averages 0.7 more ypc and 25 more ypg. He's never shown any signs of wearing down as a season progresses.
