WHO: Kansas City (7-2) at Jacksonville (6-3).
WHEN/WHERE: 1 p.m. Sunday, Alltel Stadium, Jacksonville.
THE RUB: Two of the league's best young quarterbacks square off, each with something to prove. The Chiefs' Elvis Grbac wants to show he can take Kansas City further than his predecessors. He has the team off to a quick start, but that's nothing new in Kansas City. Grbac has to show he can beat the elite, and Jacksonville remains in that category. The Jaguars snapped a two-game losing streak by beating Tennessee 30-27 on Sunday, but Mark Brunell's numbers remain low. He completed 17 of 31 passes for 169 yards. Brunell returned with a 300-yard passing effort against Pittsburgh in September, but he has not cracked that barrier since.
WHAT KANSAS CITY NEEDS: To be prepared to deal with Jacksonville's passing attack, even though it's not striking fear into opponents. Kansas City entered Monday night's game against Pittsburgh ranked 24th in pass defense, so the Chiefs will have to have an answer for WRs Jimmy Smith and Keenan McCardle. Offensively, the Chiefs must let Grbac open up against a suspect secondary.
WHAT JACKSONVILLE NEEDS: First and foremost, to replace OT Tony Boselli, who most likely will miss the next four weeks after twisting his right ankle against Tennessee. Brunell is key, but so are RBs James Stewart and Natrone Means. The Jags have to run the ball inside the 20 if they're going to succeed. The Chiefs are second in the league in red-zone defense. Jacksonville also will benefit from being home after a three-game road swing during which it lost two. The Chiefs are 3-2 on the road.
