A rebuilt offensive line has allowed a league-high 15 sacks. The revamped defense has yielded 31.3 points over the first four weeks. Opposing quarterbacks are completing 68.1 percent of their passes and Luck has accounted for five turnovers. Somewhere among the dropped passes, the constant penalties and the missing pass rush, everyone is on cleanup duty.
Here are some other things to watch Sunday:
Something the Colts know all too well.
FREEMAN'S RETURN: Indy allowed inside linebacker Jerrell Freeman to walk away in free agency after last season. Now, at a time when the Colts could really use Freeman, he'll be on the Bears' sideline. Freeman said all the right things all week, saying he never took the Colts' decision personally. Now, he'll get a chance to let his play speak volumes.
"We're going to be all right," Luck said. "We're a good football team. We practice well. We'll play well."
"We are going to keep working to try to dig ourselves out of this hole,Wholesale Football Jerseys, that's all you can do,Wholesale Kd Shoes," Colts coach Chuck Pagano said.
Eight years ago, they dominated the Colts on Lucas Oil Stadium's opening night. Four years ago, they ruined Andrew Luck's NFL debut. Another win Sunday at Indianapolis could produce an even more devastating blow to the Colts' plan — and they know it.
INDIANAPOLIS (AP) — The Chicago Bears sure know how to put a destroy Indianapolis' big days,Cheap Authentic Air Max 1.
"I think everybody was pretty disappointed in how we performed in Dallas the week prior (to last)," coach John Fox said. "I was pretty pleased with the guys' focus and how they executed against Detroit on Sunday. In this league, it's what have you done for me lately."

COLTS CHANGES: Indy cut two defensive starters Tuesday. What it will do at cornerback is clear. Projected starters, Vontae Davis and Patrick Robinson, will reclaim their jobs. The question is what happens at inside linebacker. After releasing leading tackler Sio Moore, Indy plans to use a committee of Josh McNary, Antonio Morrison and perhaps safety Clayton Geathers. Indy also could start in the no-huddle on offense.
The stakes couldn't be higher for the Colts (1-3).
Just five weeks after team owner Jim Irsay expressed hope of making the playoffs,Wholesale Jerseys China, fans are already discussing whether a fourth loss in five weeks could force a coaching change, a front office change or both. The same problems that cost them in 2015 are back.
Chicago is likely to be without starting quarterback Jay Cutler for the third straight week, leading receiver Kevin White landed on injured reserve earlier this week, and the defense is allowing 123.5 yards rushing.
But the Bears do have something working in their favor: a little momentum. Brian Hoyer, Cutler's replacement, snapped a three-game losing streak last week,Wholesale Football Jerseys China, and now Chicago returns to a city in which it has never lost.
WHITE OUT: With White out and Eddie Royal battling a calf injury, whoever starts at quarterback will need Cameron Meredith and Josh Bellamy to play well. Sure, the Bears have Alshon Jeffrey on one side. But if Royal can't play — and he didn't practice Wednesday — Meredith and Bellamy have to do better than they have so far. Meredith has six catches for 52 yards. Bellamy hasn't caught a pass.
RUNNING UPHILL: Colts running back Frank Gore moved into 10th place on the NFL's career rushing list last week and needs 20 yards to pass Jim Brown (12,312 yards). That undoubtedly will be a huge moment in Gore's career. He's also hoping to end Indy's 54-game streak without a 100-yard rusher.
MATHIS WATCH: Colts outside linebacker Robert Mathis has struggled this season. In four games, he has 10 tackles, one quarterback hit and no sacks. Some wonder if Mathis' is starting to show his age at 35 years old. Pagano still believes in his best pass rusher, saying Mathis could break out at any time. The Colts need him to make an impact now.
Could the matchup with the Bears (1-3) be just what the Colts need?
"Dropped passes are tough. False starts are tough. Bad throws are tough. I've not had a problem of not getting mad at a guy enough where I had to go yell at a guy for dropping a ball," Luck said. "It's a problem when you feel like effort isn't there and that's certainly never been the case (here)."
