Ravens vs. Chiefs: KC hopes for massive upset in NFL's Week 5

In their three losses, the Chiefs have fallen by a combined 51 points while also earning a three-point victory over the Saints. The Ravens, on the other hand, have won three games by a combined 39 points and their only loss of the season came via a one-point margin to the Eagles.

The 2012 season couldn't have begun more differently for the two teams, yet with the homefield advantage in Week 5, the Chiefs are only 5.5-point underdogs against the team tied for the AFC North lead.

To pull off the upset, though, the Chiefs will need to stop their trend of turnovers that has gotten them into trouble. In each of the first three weeks, Kansas City turned the ball over three times before a whopping six turnovers against the Chargers in Week 4.

Against a Ravens defense that has been notorious over the last decade for its ability to flip the field and give the ball back to its offense, the Chiefs' offense will have to fix its problems and end its turnover woes if the Chiefs want any chance in Week 5.
