Contain Baltimore RB Jamal Lewis

Kansas City's rush defense is ranked 29th in the league (150.3 yards per game), and two opposing running backs (Denver's Quentin Griffin and Carolina's DeShaun Foster) already have rushed for over 150 yards against the Chiefs. Now Kansas City has to face Lewis, who is fresh off of a 186-yard rushing performance against the Bengals, which included a 75-yard touchdown run. The Ravens' passing game is limited without Pro Bowl TE Todd Heap (ankle) and WR Travis Taylor (thigh).

Find Way to Spring KR Dante Hall

Hall was one of the catalysts behind the Chiefs' 9-0 start last season, setting an NFL record by scoring on a kickoff or punt return in four straight games. He leads the league with a 14-yard punt return average, but he has yet to break a big return. Still, the Ravens are fully aware of how the electric returner can change a game. In last year's 17-10 loss to Kansas City, Baltimore's special teams unit had contained Hall for much of the game, but the Ravens overplayed one lane on a fourth quarter kickoff, and Hall broke free and went 97 yards for the winning touchdown.

Avoid a Fourth-Quarter Collapse

In each of its three losses, Kansas City has been ahead or tied entering the fourth quarter, but the Chiefs have been outscored by a 34-7 margin in the final quarter of those games.

Even though the Chiefs are 0-3 for the first time since 1980, the Ravens don't expect them to roll over if faced with an early deficit. "Not this team, not with [Coach] Dick Vermeil," Baltimore Coach Brian Billick said.

"This team is the same team that was 13-3 last year. We recognize that. We respect that. It's going to be a full 60-minute game."
