it was stopping the run in the second half or giving up big plays in the passing

There are signs the Chicago Bears' defense is leaking Sam Shields Jersey Salute to Service , and it couldn't come at a worse time.Whethergame, the defense wasn't as dominant as in other games during Sunday's 30-27 loss in overtime to the New York Giants.Coach Matt Nagy thinks of it as an anomaly, but it's an issue the Bears must fix fast with the powerful Los Angeles Rams coming to Chicago on Sunday night."No, it's not a concern," Nagy said Monday at Halas Hall. "We have a lot of confidence. Our guys have tons of belief in our system; I'm talking defensively, too. They have tons of belief in our system."The system and players put the Bears (8-4) in the top five among defenses much of the season, but in Sunday's second half the Giants averaged 4.5 yards a run. Saquon Barkley finished with 125 yards, the most the Bears have given up to a running back this season."I thought for the most part overall we did a good job shutting down the run, except for a couple big plays," Nagy said. "And those 'except for a couple big plays' can get you."The most important play might have been Barkley's 22-yard run to set up a field goal before halftime, swinging momentum."Well, he is a good runner and you know he made some nice moves Authentic Brandin Cooks Jersey , he ran all over the field," Nagy said. "I felt like our guys know. Our guys are going to go back and watch the tape and say, 'Man we could have been better there. We could have made some tackles and at least cut it to a 7- or 8-yard gain, right, not a 22-yard gain.'"The Bears' defense also struggled in the second half to stop Detroit's rushing attack in the previous game, allowing 15 carries and 85 yards in a 23-16 victory."Just a little leakage," Bears linebacker Danny Trevathan said following Sunday's loss. "Nothing we can't fix. Just a little leakage."We've just got to make the plays when they come our way. We knew what type of offense we were facing, we've just got to make our plays. Our defense is way better than the way we were. We know it."The Bears have more to worry about than their run defense going up against the Rams. Their chief concern the past few weeks has been the injured throwing shoulder of starting quarterback Mitchell Trubisky.Nagy said after Sunday's loss that Trubisky remains day to day, and has improved since he started throwing Friday in practice. He wouldn't commit Trubisky's return this week after two missed games."I can't say that for sure," Nagy said. "I hope he, is but I feel like the last several days, as I told you (Sunday) was Limited Brandon Allen Jersey , he's getting better and he's feeling better."And so I think it's only fair for today, tomorrow and the next couple of days to go by that we just keep seeing him throw and see how he feels, and then he tells us."Nagy was encouraged by one improvement on offense: a better rushing attack. After going over 100 yards only once in the previous four games, the Bears ran for 118 yards against the Giants, including 76 by Jordan Howard.However, Howard had only three second-half carries."Well, the second half, they had a little plan for him," Nagy said. And so, I would've loved to be able to call more runs, but they did a pretty good job getting into our backfield and stopping the run."And then before you know it, we got behind and in overtime we started off with a run and had a nice little run there for six or seven yards. But it's hard when it's second-and-14 after a run call on first-and-10." Packers right tackle Jason Spriggs saw no need to keep going on and on about Bears linebacker Khalil Mack.There's plenty of film to watch. The rest of that Chicago defense is pretty good Ramik Wilson Jersey , too.Now Green Bay must face the NFC's top-ranked unit on the road on Sunday, a week after Chicago tripped up the high-octane Los Angeles Rams at Soldier Field."You don't have to go on and rant about how good Khalil is and all that stuff. Everybody knows who Khalil Mack is for a reason," said Spriggs, who started last week for veteran Bryan Bulaga. "I think he brings a level of confidence to everybody on the defense, and we just have to key on that and make hay when we get the chances."The right side of the Packers' line could especially be a pressure point if Spriggs, a third-year player, starts again. Bulaga missed practice again Wednesday with a knee injury.Justin McCray appears to have taken over the right guard spot after starter Byron Bell (knee) went on injured reserve Wednesday. McCray started last week. Another backup, Lucas Patrick, started at left guard for Lane Taylor, who has a foot injury.The results for Green Bay's backup-littered line were encouraging last week against Atlanta in a victory that snapped a three-game losing streak and kept slim playoff hopes alive.After allowing four sacks in the first half, the Packers (5-7-1) didn't allow one the rest of the game. Aaron Rodgers and the offense were effective throwing quick, short passes in winning Joe Philbin's debut as interim head coach and offensive play caller."I wouldn't say the concepts were basic Dante Fowler Jr Jersey Salute to Service , but I thought the flow was really good," Rodgers said. "Joe did a great job. The communication was great on the sideline and the flow was good and kind of got into a rhythm."Philbin has made it a point to mostly stick to the same routines the Packers had under fired predecessor Mike McCarthy. While it's difficult to go through a coaching change, players have said that they appreciate the relatively smooth transition."I mean, he kind of fit into the role pretty seamlessly," left tackle David Bakhtiari said. "He's done a great job adding his spin to it, yet keeping kind of the integrity of the schedule, so it's not completely different after having guys who were used to something for so long."So overall it's been pretty fluid, even in the first week," he added.There is no sense changing things up so dramatically when it will be a tough enough task to hold off the Bears.The Packers, though, do have an intangible going into Sunday that the Rams lacked: Green Bay has won eight straight at Soldier Field. The run started with Green Bay's victory in the NFC title game on Jan. 23, 2011.There's also a confidence boost that comes with the Packers' stirring rally in the season opener in September Authentic Cory Littleton Jersey , scoring 21 points in the fourth quarter for a 24-23 win over Chicago. The game marked Mack's debut with the Bears following his trade from the Oakland Raiders.Rodgers returned at halftime from a left knee injury to add to the drama The Packers went no-huddle in the second half of that game, though Rodgers stayed primarily in the pocket. It was the Packers' offense at its best."I mean getting into a rhythm, not only just as an offensive line, but just as an offense in general," Bakhtiari said about the key takeaway from that night.Rodgers is healthier now with the ability to scramble out of trouble again. Mack, who has 10 sacks and six forced fumbles, has the benefit playing nearly an entire season in the Bears' scheme. The linebacker has been mainly lining up on the right side of the defense in recent weeks, though he can easily switch sides.Respect Mack and be prepared. But don't get caught up in the star power, Spriggs said."You can't go out there and be like you're blocking God," Spriggs said. "But at the same time, you give respect where respect's due."NOTES: Taylor was limited in practice Wednesday. ... DL Kenny Clark (elbow) and CB Bashaud Breeland (groin/not injury related) missed practice.
