KANSAS CITY Marlon Mack Jersey , Mo. 鈥?The Kansas City Chiefs‘ defense had been hearing all season about how bad it was, and how聽it was the biggest threat to an offensive juggernaut falling short of the Super Bowl.Then聽it shut down the Oakland Raiders in Week 17.Now, the Raiders are hardly one of the NFL's premier offenses, and they rolled into Arrowhead Stadium with little impetus to play hard. But by holding Derek Carr and the rest of the Oakland offense in check, it gave the Chiefs some positive momentum heading into the playoffs, not to mention proof that some subtle tweaks to their personnel packages had paid dividends."We just have to keep it rolling," said linebacker Justin Houston,聽the defense's longtime emotional leader. "It's a great time for us to play like this. We were firing on all cylinders from the front to the back end (against Oakland), and now we just have to build off it."That's because Andrew Luck and the rest of the Indianapolis Colts, who come to Kansas City for the divisional round Saturday, represent a massive upgrade in competition.Luck threw the second-most touchdown passes in the NFL this season, behind the Chiefs' Patrick Mahomes, and聽played behind one of the best offensive lines in the league.The Indy offense isn't a one-trick pony, either.聽The Colts dominated the Texans on the ground in a 21-7 win in the wild-card round as聽Marlon Mack piled up 148 yards rushing and a touchdown.The Colts have roared into the postseason with seven wins in eight games."Andrew's going to get you every once in a while," Chiefs coach Andy Reid said, "and you've got to make sure you get him more than he gets you, but he's got a lot of good players around him. That offensive line, people can argue with you that it's the best in the National Football League. You look at the receivers Quenton Nelson Color Rush Jersey , they've got good receivers, they've got good tight ends, you go all the way around."You've got to bring your best. That's what the playoffs are all about," Reid added. "This is the best in the National Football League, which is the best in the world, and you have an opportunity to do that. That's an exciting thing, but you better bring your best every play."The question for the Chiefs is simple, though: Is their best good enough?Indianapolis was fifth in scoring while the Chiefs were 24th in scoring defense. They were last in the league in rush defensive efficiency, average yards after contact and first-down percentage, and they were second-to-last in yards-per-carry allowed despite many teams trying to play catch-up.As bad as those numbers were, though, the Chiefs were actually respectable against the pass. And they were downright dominant when it came to pressuring the quarterback, generating sacks on 7.4 percent of pass plays 鈥?better even than Khalil Mack and the Bears 鈥?and pressure on 31.1 percent of them.That聽sets the stage for an intriguing matchup between the聽Indy offensive line, which has allowed no more than one sack in a game since Week 4, and the Chiefs' dominant pass rush."The goal and strategy remains the same," Colts offensive coordinator Nick Sirianni said. "Run the football and set up other things by running it, and then be successful in situational football."The Chiefs made some key personnel changes late in the season, effectively benching veteran safety Ron Parker and cornerback Orlando Scandrick. Daniel Sorensen https://www.coltsfanshop.com/Andrew-Luck-Jersey , Charvarius Ward and Jordan Lucas have been playing more, and their results against woebegone Oakland were encouraging.The Chiefs also could get safety Eric Berry back after he missed Week 17 with a recurrence of his heel injury. Berry played only two games this season, but he changed the entire dynamic of the Kansas City defense for the snaps he was on the field."We've just got to lock in," Chiefs cornerback Kendall Fuller said. "For us, we're inside this building. That's the only thing we're focusing on. I'm not a big social media guy. We just come together week-in and week-out, to win on Saturday. We just keep it in-house and focus on each other."NOTES: Berry and WR Sammy Watkins (foot) participated in the portion of practice open to the media Tuesday. DT Derrick Nnaddi (concussion) also said that he'd been cleared to rejoin practice. … OLB Dorian O'Daniel did not practice because of a calf and ankle injury.100View Gallery Gallery:View from the sidelines: NFL cheerleaders 2018Raj Mehta-USA TODAY Sports | Raj Mehta INDIANAPOLIS (AP) — Andrew Luck traipses across the locker room with a little extra pep in his step these days.It’s obvious from the smile that the Indianapolis Colts‘ starting quarterback is content to put on his shoulder pads, prepare for practice and get ready to make his first regular-season start in more than 20 months.Sure, there were times Luck questioned when or even if this day would come, whether he could regain the Pro Bowl form from his first three pro seasons after shoulder surgery and whether those regular pregame jitters he craves would again be part of his game-day routine.Now, just a few days away from facing Cincinnati’s defense, Luck looks and sounds like the confident leader everyone expects him to be this season.“I think everybody knows how great a quarterback he is. He’s been out for a little while so I think they’re probably waiting to see if he’s back, healthy, ready to go,” kicker Adam Vinatieri said. “Everything that we’ve seen this offseason through minicamp, training camp tells me he’s ready to rock and roll and be the Andrew we all know he can be.”Luck understands just how heavily scrutinized these first few games will be.He anticipates a litany of questions about his health, the subtle changes he’s made to his throwing motion after working out with former major league pitcher Tom House, his ability to bounce up after big hits and whether using the sidelines and baseball slides will change his approach to the game.After all, it was the hit he took from behind in the third preseason game that caused a minor foot injury that forced him out of two practices last week. But the fact he is talking about his foot rather than lingering pain in his right shoulder certainly is a sign of progress.“Certainly not as smooth (a recovery) as you’d like Josh Ferguson Jersey ,” he said Wednesday, referring to his recovery from the surgery on a partially torn labrum in January 2017. “There have been hiccups and there have been challenges and hurdles to go over and frustrating times, and as a team, too. But I feel like we’ve always managed to find a way through it.”The darkest moments appeared to come after Luck shut down his throwing regimen and went on injured reserve last fall.He spent several weeks seeking additional opinions to determine whether a second procedure was necessary. Once assured nothing was structurally wrong, Luck headed to the Netherlands in November where he worked for more than a month working with a trusted trainer in relative anonymity.When he returned to the team complex in late December, Luck was clearly a frustrated man.“There was a time, probably a couple weeks into being away from here, in early December that was pretty difficult for me to sort of see the positive in things,” he said on Dec. 29. “You get a little emotionally tired. I am, I think, a little emotionally tired from the whole process. But that’s all right.”Teammates understood.“It’s a lonely feeling in this league when you get hurt and you can’t be out there with your teammates, for your coaches, for your fans,” tight end Jack Doyle said. “So when I think he got back around us and practicing and just playing football again, you really saw him come back to normal, I guess.”It took more than five months to see actual results.Luck resumed throwing footballs in May, a secret he kept by swearing first-year coach Frank Reich to silence.Then, on the second day of Indy’s three-day minicamp Luck made a surprise return and began flinging footballs around the practice field for the first time since October.Suddenly T.J. Green Color Rush Jersey , the conversations changed throughout the city.Reich and general manager Chris Ballard outlined a training camp plan that called for Luck to mimic his regular-season routine by throwing three times per week in non-game settings.Luck’s brief appearance in the preseason opener at Seattle eased most doubts about whether he’d start the season opener.His ability to survive big hits in each of the first three preseason games proved to fans, coaches and critics he was healthy. And if any additional assurances were needed, teammates found them in Luck’s demeanor on and off the field.“Seeing him finally come out in camp and just have that confidence back, it really is a lot of fun,” center Ryan Kelly said. “Being able to laugh and joke around, I’m sure a year ago even if he had been playing he didn’t have that in him. So it’s kind of like a reset button for him and it’s fun.”Now Luck must deal with yet another test.He faces a Bengals defense that includes sacks artists such as Geno Atkins, Michael Johnson, Carlos Dunlap and Carl Lawson with the possibility of playing behind two new tackles.Longtime left tackle Anthony Castonzo did limited work in practice Wednesday and his status for Sunday’s game remains unclear. Reich said he’s decided on a starter at right tackle, but won’t make an announcement till Sunday.Still, Luck isn’t fretting.He knows he’s endured tougher predicaments and experienced more mentally challenging moments over the past 20 months while rediscovering his passion for the game. And he can’t wait for the moment, Saturday night or Sunday morning, when his stomach tightens and those nerves start firing.“I think those butterflies will always be there,” he said with a smile. “It’s a special feeling and I’ve missed that feeling.”
