Week 11 N.F.L. Matchups - NYTimes.com 8:25 p.m. Line: Broncos by 8 Known for having one of the loudest home stadiums in the league, Kansas City has somewhat quietly remained the N.F.L."s only unbeaten team. It may not seem fair that Denver is drawing far more attention than the division-rival Chiefs. But it is more exciting to watch Broncos tight end Julius Thomas execute a gorgeous catch-and-run for a 74-yard touchdown, as he did in Week 10, than to watch the Chiefs plug away with a quietly efficient offense and a defense that is the hardest to score against in the N.F.L. Looking to stay perfect, Kansas City may catch a break because Peyton Manning further injured his ankle, making him even slower on his feet than usual. That will be music to the ears of Justin Houston and Tamba Hali, who have combined for 20 of the Chiefs" league-leading 36 sacks. Denver has a lot of threats on offense, and is especially tough at home. But the Chiefs are no fluke, and if they can neutralize Manning, they could be 10-0 for the first time in franchise history. 49ers (6-3) at Saints (7-2) 4:25 p.m. Sunday Line: Saints by 3 Since Drew Brees arrived in New Orleans, pinning down his favorite receiver from week to week has been an exercise in frustration. He can seemingly create a new star in each game. San Francisco's Colin Kaepernick drew recent criticism from Trent Dilfer, a former 49ers backup. Dilfer said Kaepernick becomes a remedial quarterback when his first read on a play is covered. In fairness to Kaepernick, he has spent most of the season with only one capable wide receiver, Anquan Boldin. So opponents have blanketed the less-than-speedy Boldin on every play, and he has not been able to get going alone. Mario Manningham returned from injury in Week 10, and Michael Crabtree is expected back soon. But a road game against the Saints, without the star tight end Vernon Davis (concussion), will probably mean this is not be the game for Kaepernick to prove Dilfer wrong. Vikings (2-7) at Seahawks (9-1) Sunday Line: Seahawks by 12 Even if Percy Harvin serves mostly as a decoy in his first action since the middle of last season, it will be a welcome addition for dominant Seattle. As good as the Seahawks have been, a season-ending injury to Sidney Rice has limited their passing options. Having the versatile Harvin on the field should help Doug Baldwin and Golden Tate, both of whom can do damage if they get open. The prospect of improvement for Seattle's offense is great news for a team hoping for a long playoff run. But nothing dramatic should be required to beat a terrible Minnesota team. Ravens (4-5) at Bears (5-4) Sunday Line: Bears by 3 Chicago's injury report is filled with big names like Jay Cutler, Lance Briggs and Charles Tillman. And the Ravens may be looking at this game as the chance to win at Soldier Field for the first time (unless you count the Cleveland Browns, who beat the Bears on the road in 1954 and 1969, then moved to Baltimore in 1996). The Ravens might not want to get overly excited. Josh McCown has proved to be a reliable backup for Cutler, and Matt Forte anchors a strong Bears running game, which should lead to plenty of points for Chicago. Baltimore, with no running game to speak of and Joe Flacco prone to turnovers, will struggle to keep up. Pick: Bears Jets (5-4) at Bills (3-7) Sunday Line: Bills by 1 The Jets" season has made little to no sense. A bad offense and a defense that allows far too many points have somehow led to a winning record, including huge upsets against New England and New Orleans. They have followed each win this season with a loss. The Jets" lack of consistency can be largely attributed to Geno Smith, their rookie quarterback, whose turnovers have often negated a solid running game. Following their pattern, the Jets might as well lose to Buffalo and set an N.F.L. record for alternating wins and losses. Pick: Bills Redskins (3-6) at Eagles (5-5) Sunday Line: Eagles by 5 Nick Foles may not seem like the ideal quarterback for Chip Kelly's up-tempo Philadelphia offense, but his 16 touchdowns and no interceptions this season seem to show he is a good fit. Although Foles, a second-year player out of Arizona, will probably come back to earth soon, there is no reason to believe that will happen against a Washington defense that has allowed the second-most points a game in the N.F.L.
