HOUSTON (AP) 鈥?A year ago at this time Andrew Luck was at home struggling

with an injured shoulder that cost him the entire season.On Saturday he wrote a happy ending to the latest chapter of his comeback season https://www.coltsfanshop.com/Andrew-Luck-Jersey , throwing for 222 yards and two touchdowns and the Indianapolis Colts raced out to a big lead and cruised to a 21-7 win over the Houston Texans in the wild-card game.Luck put on a show聽in his hometown in a stadium where he'd attended games throughout childhood and played in them since high school, throwing for 191 yards and two touchdowns before halftime to help the Colts (11-6) build a 21-0 lead.He denied feeling "at home" at NRG Stadium, but admitted to having warm feelings for the city he grew up in and where his grandparents and many friends still reside."But it's still an away stadium," he said. "It was very loud, very energetic, but fun to win, certainly."Running back Marlon Mack had 148 yards and a touchdown for Indianapolis, which advances to face the top-seeded Kansas City Chiefs in the divisional round next weekend."We know we have an elite quarterback and we can throw it for 400 and win when we have to," Indianapolis coach Frank Reich said."But the margin for error in playoff football when you try to do it that way is very thin. When you can win like this 鈥?running the football and stopping it 鈥?that's just everything."Houston (11-6), which overcame a 0-3 start to win the AFC South, gave up too many big plays and couldn't get anything going on offense in the first half to fall into the huge hole.Deshaun Watson, who was sacked an NFL-leading 62 times in the regular season, was sacked three times and hit eight more times in a disappointing playoff debut. He finished with 235 yards passing with a touchdown and an interception."Just a lack of execution on our part," Watson said. "We didn't make plays. I didn't make plays. Communication was a little off. You just got to give the Colts the credit."The Colts, who opened the season 1-5, continued an impressive run by winning their fifth straight and for the 10th time in 11 games. Saturday was their first playoff appearance since the AFC championship game loss at New England in the "Deflategate" game in the 2014 season.It was another good game in a splendid season for Luck. He threw for 4 Josh Ferguson Jersey ,593 yards and 39 touchdowns in the regular season after missing all of 2017 with a shoulder injury.The Texans didn't score until rookie Keke Coutee聽grabbed a 6-yard touchdown pass聽to cap a 16-play, 89-yard drive that included a fourth-down conversion that cut it to 21-7 with about 11 minutes left.They led the NFL with nine comeback wins this season, but their attempt at a rally ended on their next possession when Watson's pass on fourth-and-10 from the Indianapolis 24 fell short with about four minutes left.Luck threw for 863 yards with six touchdowns as the teams split two meetings in the regular season. He picked up right where he left off in this one, when he found Eric Ebron on a 6-yard TD pass on their first drive. That play was set up by a 38-yard catch by T.Y. Hilton, who had 63 yards receiving on that drive."We didn't have a lot of guys that made the playoffs so the guys that made the playoffs wanted to go out there and set the tone early, try to get the crowd out of the game," Hilton said. "That's what we did."Hilton didn't have any catches on the next drive, but the Colts still drove down the field easily and made it 14-0 on a 2-yard run by Mack later in the first.Houston went for it on fourth-and-4 from the Indianapolis 45 on its second possession and Watson was intercepted by Kenny Moore II. It was his first interception since he threw two against the Redskins on Nov. 18.The Colts got to the 17 after that before J.J. Watt deflected Luck's pass and he was intercepted by Brandon Dunn. But the Texans couldn't move the ball and had to punt.Indianapolis pushed the lead to 21-0 when Luck connected with Dontrelle Inman on an 18-yard touchdown pass in the second quarter."It's very frustrating when they're able to execute and get their job done," Watt said. "We had a couple of big penalties early in the game as well. But you have to overcome it and you have to find a way to win."The Texans had a fourth-and-1 from the 9 late in the second quarter and went for it again instead of settling for a field goal. The gamble didn't pay off when Watson's pass to DeAndre Hopkins was low and bounced in front of him in the end zone.INJURIESColts: Safety Malik Hooker left in the third quarter with a foot injury. … S Mike Mitchell injured his calf in the third quarter and didn't return.Texans: Safety Justin Reid injured his ribs in the second quarter and didn't return. … Hopkins said he played most of the game with a Grade 3 AC sprain of his right shoulder after injuring it in the first half.UP NEXTColts: Travel to Kansas City where the Chiefs were 7-1 in the regular season.Texans: The Texans have some decisions to make in the offseason with defensive end Jadeveon Clowney and safety Tyrann Mathieu both becoming free agents. They might use the franchise tag to keep Clowney, who was the No. 1 overall pick in the 2014 draft. INDIANAPOLIS 鈥?The Indianapolis Colts‘ defense was reeling early this season.After six games, it had allowed an average of 30 points, had given up 37 or more points in three consecutive losses, was languishing near the bottom of the league's overall rankings and showed no sign of a turnaround.Today, those performances are almost unrecognizable. Though the names remain essentially unchanged, the Colts overcame that dismal start and have emerged as one of the NFL's stingiest units and a key cog in Indy's playoff run."We feel good, we've been rolling T.J. Green Color Rush Jersey ," rookie linebacker Darius Leonard said. "We just want to keep it going. We want to keep everything rolling." Leonard and his teammates face their biggest challenge yet in Saturday's divisional-round game at Kansas City. But the timing couldn't be better for a young, suddenly sturdy defense that still has plenty to prove.Over the past six weeks, the Colts have given up 12.0 points per game, posted their first shutout in four years and ascended to No. 11 in the rankings. But many wonder whether the defense can hold up against the league's highest-scoring team.So far, Indy (11-6) has passed every test. The defense has played a vital role in two five-game winning streaks. Indy is one of two teams that have not allowed a 100-yard rusher this season and have had at least one turnover in 16 of 17 games.Outsiders have noticed the turnaround by a unit once regarded as a weak link."I think the players have bought in and they play hard," Chiefs coach Andy Reid said. "They're accurate with their assignments."Reid isn't alone.Leonard, the league's leading tackler, was named first-team All-Pro last week, and first-year defensive coordinator Matt Eberflus interviewed Sunday for the Cleveland Browns' head coaching job. Though he wasn't hired, the dramatic ascension could help Eberflus stay on the coaching radar.What's changed? Not much personnel-wise from opening day.Defensive tackle Al Woods and linebacker Skai Moore both wound up on injured reserve. Margus Hunt moved from defensive end to defensive tackle and Pierre Desir claimed one of the starting cornerback spots. Otherwise, the lineup remained as consistent as Eberflus' message."When you keep doing the same things over and over again and you get good at the fundamentals of the game, then you can start adding a little bit to your package because the guys understand the basics," Eberflus said."You can never move on or never forget the basics of what your system is about. That to me is the hustle, the intensity, taking the ball away and being smart players."Eberflus, initially hired by Josh McDaniels and retained by Frank Reich after McDaniels backed out of the job https://www.coltsfanshop.com/Matthias-Farley-Jersey , scrapped the 3-4 defensive front from previous coaching staff and installed the Tampa-2 preferred by general manager Chris Ballard.Reich was on board, too, remembering how the system helped the Colts win a Super Bowl during his first stint with the team.The scheme relies largely on speed and trust and was a perfect fit for a team trying to rebuild. Only three full-time starters returned in the same spot this season while a fourth, Jabaal Sheard, moved from outside linebacker to defensive end, but the simplicity shortened the learning curve for everyone, including the youngsters.And after six games, things started to mesh. Leonard became the breakout star, the pass rush became more consistent and the run defense tightened up."We go into this game knowing that we can beat the best," Leonard said. "Once you go in as an underdog, there's a lot more chips on your shoulder. It makes you want to play harder. It makes you want to win more."NOTES: Four-time Pro Bowl receiver T.Y. Hilton (ankle) is one of five players who did not practice Wednesday. The others are defensive tackle Denico Autry (shoulder), receiver Ryan Grant (toe), safety Malik Hooker (hip/foot) and defensive end Tyquan Lewis (knee). Hilton expects to play. … Tight end Eric Ebron (hip), receiver Dontrelle Inman (shoulder/finger) and Sheard (knee) were limited in practice.
