Chiefs quarterback Matt Cassel has heard his fair share of criticism in Kansas City this season, and for good reason. In four games, he's thrown seven interceptions and fumbled the ball four times. Ball security has been an issue with Cassel, one that has quite possibly kept the Chiefs from having at least a .500 record.

But the Ravens aren't taking the Chiefs signal caller lightly. From film, they still a capable quarterback who can hurt them in a lot of ways.

"I think with his legs he can get outside the pocket and he can run a little bit, and he can throw the ball," safety Bernard Pollard said. "He has talented guys to throw the ball to."

As Pollard said, there isn't a shortage of skill position talent on the Chiefs roster. Receiver Dwayne Bowe already has 342 yards and three touchdowns. Jonathan Baldwin is a big, speedy receiver on the outside. Dexter McCluster is shifty in the slot and Steve Breaston has been a formidable NFL receiver in the past.

The missing link from Kansas City's offense turning into a dominant unit has been Cassel, thanks to his turnovers. If he eliminates the mistakes and plays smarter with the ball, the Chiefs could be a dangerous team at home this Sunday.

Through the first quarter of the season, the Ravens have been opportunistic enough to come up with seven turnovers (four interceptions, three fumbles) despite allowing 390.2 yards per game.

Continuing to force Cassel turnovers will be key for Baltimore.

"If you let him sit in the pocket, he can make a day hard for you," linebacker Ray Lewis said. "He's got a lot of weapons around him, all the way around him actually. They added a lot of new pieces and I just think they're doing a great job. You take away the turnovers and they're doing an awfully great job with their offense."

The Chiefs are minus-13 in turnover margin, which ranks last in the NFL in that category. Ravens defensive coordinator Dean Pees said his unit is mindful of Kansas City's tendency to turn the ball over. But Pees said it's not something he's stressing too much in the meeting room.

"I think we are an aggressive defense, and hopefully, if you’re an aggressive defense and you keep getting guys to the ball, you’re going to create turnovers," Pees said. "I don’t think it’s anything where you are deliberately going out and saying, ‘Well, this week they are more turnover prone so we are going to do this and this.’ Hopefully, they stay that way.”
