KANSAS CITY, Mo. -- There is an argument to be made that the AFC West is the best division in the NFL.There is little argument to be made that the Chiefs are the class of it.After dispatching the Raiders on a frigid night at Arrowhead Stadium, the Chiefs are tied with them for the lead at 10-3 with three games left in the regular season. But they hold the tiebreaker thanks to two head-to-head wins over Oakland, which could loom large down the stretch.For the division title, sure. But also for a first-round bye in the playoffs.Every division game has got to be a playoff game. Its going to be something more, Chiefs tight end Travis Kelce said after the 21-13 victory on Thursday night, especially with a team like Oakland thats at the top of the charts on offense and defense.Well, they had been at the top of the charts heading into the showdown.The Chiefs knocked them down a peg.It was their fifth straight win against the Raiders and their ninth consecutive victory over division foes, the third-longest streak in franchise history. Along the way are not only the two wins over Oakland this year, but also a win in Denver -- the other divisional team in the thick of the postseason hunt heading into the Broncos game Sunday at Tennessee.The Broncos visit Arrowhead Stadium on Christmas night.Its all about us. Its not about who we play, said star pass rusher Justin Houston, whose return from offseason knee surgery has given the Kansas City defense a big midseason lift.We just need to stay focused, he said. This win means a lot to us, but the seasons not over. We need to put this game behind us, stay focused, and finish the rest of the season strong.Thats because there is still plenty on the horizon.The Chiefs havent won the AFC West since 2010, when they finished 10-6 in a division that it seemed nobody wanted to win. Their many deficiencies showed when they were routed 30-7 by Baltimore in their first playoff game, which they hosted because of their division title.Their last two playoff trips have started on the road as wild cards.Three years ago, they went to Indianapolis and built a big early lead before their defense melted down in the second half. And last year, they went to Houston and came away with their first playoff victory in more than two decades, only to lose at New England the following week.So to say that a first-round bye and a home playoff game in the second round are crucial would be an understatement. They are more like necessities for a team dreaming of a Super Bowl.Its good right now, Chiefs running back Spencer Ware said, but we cant get comfortable. Weve got to keep our eyes on the prize and stay focused on the main goal.That goal became a little more challenging when the Chiefs lost Derrick Johnson, their veteran linebacker, to a ruptured Achilles tendon in his left leg. Johnson went down untouched late in the first half Sunday and, it seemed, knew right away his season was over.Still, the Chiefs rallied around their fallen leader. Their defense repelled Oakland throughout the second half, even when their own offense was stumbling, and did enough to keep Derek Carr and Co. out of the end zone late in the game to preserve the critical victory.The result? The Chiefs assured themselves a second straight 10-win season, something the club has only accomplished two other times in franchise history. And that nine-game win streak of division foes is currently the best in the NFL, though Houston can match it with a win over Indianapolis on Sunday.But the Texans are only 6-6 overall. The Chiefs are 10-3 and barreling toward bigger things, their future looking the brightest it has all season after their Thursday night win over Oakland.Were trying to get to our ultimate goal, Chiefs cornerback Marcus Peters said, so we have to win, individually, each game. So were going to prepare for our next opponent and just keep moving on.Game notes Chiefs coach Andy Reid said Friday that general manager John Dorsey is poring through options to replace Johnson, but no decisions have been made. We know we have a few guys that can play, Reid said. We havent made any decisions, dont have anybody coming in as of yet. ... Reid didnt have any update on DT Rakeem Nunez-Roches, who left with back spasms, or DE Kendall Reyes, who sprained his wrist.---For more NFL coverage: http://www.pro32.ap.org and http://www.twitter.com/AP-NFLJohn Collins Jersey .

Defenceman Yannick Weber scored the go-ahead goal early in the third period and the Canucks breathed a sigh of relief with a 2-1 win on Saturday night.Arsene Wenger said Arsenal lacked confidence to score a second goal after they were held to a 1-1 draw by Crystal Palace on Sunday. Alexis Sanchez put the Gunners ahead late in the first half at the Emirates but they were pegged back by Yannick Bolasie in the 81st minute. Air of apathy at Arsenal Alan Smith: Arsenal need to answer questions after awful end to season Despite having 21 shots on goal, the hosts could not add to their tally and their title hopes are now all but gone, with Premier League leaders Leicester 13 points ahead and only five games left to play. It is a bad result, Wenger told Sky Sports. We had plenty of possession, but did not create enough clear-cut chances. We lacked a change of pace and our passing was a bit slow. Former strikers Alan Smith and Thierry Henry discuss Arsenals struggles Overall, we were unlucky ass they had one shot at goal, but maybe there was a lack of confidence to really go for it.ddddddddddddAsked whether Petr Cech could have done better with Bolasies shot, which beat him at his near post, Wenger said: I have to look at it again. It didnt look unstoppable but he will know that better than I do.Maybe we could have stopped the shot, but I will have to see it again. Should Arsenal goalkeeper Petr Cech have kept out Yannick Bolasies long-range shot? The goal earned Crystal Palace a 1-1 draw at The Emirates Arsenal will now turn their turn attentions to another home game against West Brom on Thursday as they look to cement their spot in the top four.We have to regroup and recover for the next game, and not look too far ahead, said Wenger. Today we have made it more difficult for ourselves. We have to focus and try to win the next game. Also See: Arsenal 1-1 C Palace As it happened Arsenal fixtures Get a £10 free bet! ' ' '
