The Indianapolis Colts defense was reeling early this season Briean Boddy-Calhoun Jersey.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 leagues overall rankings and showed no sign of a turnaround.Today, those performances are almost recognizable. Though the names remain essentially unchanged, the Colts overcame that dismal start and have emerged as one of the NFLs stingiest units and a key cog in Indys playoff run Rigoberto Sanchez Jersey. We feel good, weve been rolling, 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 Saturdays divisional-round game at Kansas City. But the timing couldnt 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 leagues highest-scoring team.So far, Indy 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. Theyre accurate with their assignments.Reid isnt alone.Leonard, the leagues 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 wasnt hired, the dramatic ascension could help Eberflus stay on the coaching radar.Whats changed Not much personnel-wise from opening day.Defensive tackle Al Woods and linebacker Skai Moore both wound up on injured reserve Farrod Green Jersey. 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, 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, theres 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.
