Halfway through Steve Wilks' initial season as head coach Youth Nasir Adderley Jersey , the Arizona Cardinals have two victories. Things get tougher from here on out. After taking this weekend off, the Cardinals play at Kansas City. The schedule also features games at the Los Angeles Chargers, Green Bay and Atlanta. And there's that final home game against the Los Angeles Rams.So wins are going to be hard to come by for a team that sputtered to a 2-6 start, topping 20 points in a game only once. So the main focus from this point forward is developing rookie quarterback Josh Rosen.To offensive coordinator Byron Leftwich, Rosen is simply "the kid.""The kid can really play," Leftwich said. "His demeanor allows him to have success. Quarterbacking in this league is hard and when things go bad this kid tends to be fine. He's OK in those situations. Like I said, he can really play and it's just my job to get him in position that he's doing the right things."Leftwich knows Rosen well. He was the quarterbacks coach before being promoted to coordinator after Mike McCoy was fired seven games into the season."I'm just trying to get him better," Leftwich said. "Our goal is to come out here and get this kid better every day in every form and fashion. There's not any specifics. I'm working on this kid the whole way, the whole way we're just trying to install the things we need to install in him so this kid could be playing 15 or 20 years."Rosen took over the worst offense in the league late in the third game of the season (a home loss to Chicago) and has held the job ever since. He didn't talk to reporters this week but praised Leftwich after Sunday's 18-15 come-from-behind win over the 49ers."The one thing I think Byron is really good with is his demeanor," Rosen said. "He's played the game, he's been in a lot of big-time situations, so I think he has really good timing with a lot of his play calls, he's got really good poise. He's a steading force for us on offense."The Arizona offense sputtered for three quarters before Rosen threw two fourth-quarter touchdowns, a 13-yarder to Larry Fitzgerald and the game-winner, a 9-yarder to the back of the end zone to fellow rookie Christian Kirk Cheap Nasir Adderley Jersey , with 34 seconds to play.The Cardinals were able to get running back David Johnson into open space a little bit more than they had, and the defense shut down San Francisco's strong running game most of the afternoon.Wilks, whose coaching experience is entirely on the defensive side of the ball, likes what he's seen from Leftwich, who played nine seasons at quarterback in the NFL but is a relative newcomer to coaching."I think he's going to continue to try to be creative in his approach and really try to put the guys in a position to be successful," Wilks said.Rosen approaches the coming weeks with that even-keeled confidence even though Leftwich is his fifth coordinator in four years, counting his time at UCLA.The Cardinals also try to move on from the distraction of three-time All-Pro cornerback Patrick Peterson's request to be traded. He backed off the request after a meeting with team president Michael Bidwill and has two years left on his contract.Wilks called on Peterson to speak in the huddle after the San Francisco win."What was said and what was talked about last week is in the past," Wilks said. "Patrick is a captain. He's a leader on this football team. Again, I want him to have a voice, and that's what he wanted to do, and I gave him that opportunity."Notes: Wilks said he expects DT Corey Peters (ankle) and RG Justin Pugh (hand) to be back next week. KANSAS CITY, Mo. (AP) — Arrowhead Stadium was already emptying by the time Chargers quarterback Philip Rivers jogged to the locker room, triumphantly waving his hand as a satisfying cascade of boos washed over him.He had finally beaten the Kansas City Chiefs.It sounded perfect.Rivers led Los Angeles on a feverish fourth-quarter comeback Thursday night, capped by a debatable pass-interference call, a tense video review of the last touchdown and the gutsy decision to try a 2-point conversion. And for the first time in years against Kansas City White Nasir Adderley Jersey , everything turned out perfectly for Rivers and the Chargers in a 29-28 victory that clinched their playoff spot.“This was big. Here or at home, whatever,” Rivers said, “we needed to beat these guys.”The Chargers (11-3) trailed 28-14 when Justin Jackson’s touchdown run with 3:49 to go gave them a chance. They quickly got the ball back from Patrick Mahomes and the NFL’s highest-scoring offense, and Rivers led a tense final drive that included a fourth-down dart to Travis Benjamin to keep it alive.That crucial penalty on Kendall Fuller in the back of the end zone gave the Chargers the ball at the 1, and Rivers found Mike Williams along the sideline on the next play. And when his TD catch with 4 seconds left was confirmed, coach Anthony Lynn sent his offense back onto the field.Williams hauled in the conversion to end five years’ worth of frustration.“We didn’t come here to tie. We came here to win. So to me it was a no-brainer,” said Lynn, whose team became the first since Minnesota in Week 15 of the 2002 season to win with a 2-point conversion in the final 10 seconds of regulation.The comeback allowed Los Angeles to forge a first-place tie in the AFC West, though the Chiefs (11-3) hold the tiebreaker with a better division record. More satisfying was the simple fact that Rivers and the Chargers had finally snapped their nine-game losing streak against Kansas City.They hadn’t beaten the Chiefs since 2013, the last year they made the playoffs.“Oh, it’s satisfying,” Benjamin said. “We talked about it. We knew it had been a couple years and we wanted to go into this game and change that and we did.”Rivers threw for 313 yards and two touchdowns with two interceptions, and Williams had seven catches for 76 yards and two scores while adding another on the ground. Jackson ran for 58 yards and a touchdown in place of the injured Melvin Gordon and Austin Ekeler.Mahomes was held to just 243 yards and two touchdowns for Kansas City, and his inability to pick up a first down in the closing minutes proved costly. The Chiefs forced the Chargers to burn two timeouts on their last drive Nasir Adderley Los Angeles Chargers Jerseys , but Mahomes was sacked by Isaac Rochell and Kansas City had to punt.The Chiefs never got the ball back on offense.“They found a way to win and we didn’t,” Mahomes said. “You have to find a way in this league.”Hyped by the return of star safety Eric Berry, it looked for a while as if the Chiefs would simply resume their vexation of Rivers at Arrowhead. Steven Nelson leaped to snag a jump ball for a pick on the second play of the game, and Rivers tossed another just before halftime.Mahomes and Co. took advantage of their early momentum.Kansas City breezed downfield after Nelson’s interception, and the young MVP candidate threw a dart to Demarcus Robinson — while in the grasp of Chargers safety Adrian Phillips — for a 7-0 lead.Then after a punt, Darrel Williams took a screen pass for his first career touchdown.The Chargers finally reached the end zone in the second quarter, when Mike Williams caught a short TD pass. But it came moments after wide receiver Keenan Allen hurt his hip while trying to make a leaping grab in the corner of the end zone — he briefly returned before sitting out the rest of the game.Mike Williams continued to pick up the slack the rest of the game.After the Chiefs pushed their lead to 21-7 on Damien Williams‘ touchdown run, the Chargers’ big, rangy wide receiver answered with a 19-yard end-around for a score. And when then Chiefs went on another methodical scoring drive to take a 28-14 lead with just over 8 minutes left in the game, Mike Williams helped to lead the Chargers to an answering touchdown to stay in the game.He made two more big catches in the final seconds to put them over the top.“Everybody needed to come together and make plays,” Mike Williams said, “and that’s what we did.TONY G’S AWARDThe Chiefs added TE Tony Gonzalez to their Hall of Fame at halftime. The six-time All-Pro played his first 12 seasons with the Chiefs before finishing his career in Atlanta. His name was unveiled next to that of WR Carlos Carson on the ring of honor inside Arrowhead Stadium.INACTIVE STARSGordon (knee) tried to warmup before telling Lynn he couldn’t play, joining Ekeler (concussion) on their inactive list. The Chiefs were missing RB Spencer Ware (hamstring) and WR Sammy Watkins (foot).INJURIESChargers: Allen received treatment on the sideline after nearly making his spectacular TD catch, and he returned briefly before slowly walking off. He left for the locker room and did not return.UP NEXTChargers: Return home for a prime-time game against the Ravens on Dec. 22.Chiefs: Visit the Seahawks for another prime-time game Dec. 23.
