This line is ugly for Denver, but I'm going on a hunch that Denver wins this one big.
The main reason Denver didn't win or cover in the first game at Kansascity was due to 4 turnovers, 2 in the 1st quarter alone. I don't see them playing that recklessly again after what happened in that Raiders game. Shanahan will game plan better this time and take advantage of that Chiefs youthful secondary like he did in the Jets game. With Champ Bailey back, this should greatly boasted that injured riddle secondary going against Rookie QB Tyler Thigpen. Their will be turnovers committed by the Chiefs in this game, that's why I think Denver should cover the -9 pointspread. Plus, Denver has covered majority of their games against KC at home anyways.
