LAKE FOREST Bobby Massie Jersey , Ill. (AP) — The Chicago Bears are in wait-and-see mode with Kyle Long.Coach Matt Nagy said Monday that Long remains in the evaluation process and he hopes to know more in the next day or two after the offensive lineman left Chicago’s 24-10 victory over the New York Jets with a right foot injury.The 29-year-old Long was selected by the Bears in the first round of the 2013 draft and made the Pro Bowl in his first three seasons. But he was hampered by injuries in each of the previous two years, resulting in right ankle surgery following the 2016 season and operations on his shoulder, elbow and neck after he was shut down late last year.“For him to go through what he’s gone through the last couple years with injuries, you feel for the guy,” said Nagy, who is in his first season with the Bears.“Like I said, he’s been doing really well. Since our first day together in OTAs he’s been a constant leader. He’s very engaged in meetings. He’s just really done things the right way.“So right now, we’re hoping that it’s good news. But we won’t know here for a little bit.”Long got hurt when tight end Dion Sims rolled into him while the two were blocking for Jordan Howard on a run in the fourth quarter. Nagy said it’s a foot injury and not an aggravation of his previous trouble with his right ankle.“It’s one of those ones that could be a little time, but I don’t know if it’s necessarily season-ending,” he said.Long’s injury put a damper on an important victory for Chicago (4-3), which had dropped two in a row.Minnesota, Green Bay and Detroit all lost Sunday, putting the Bears back on top of the congested NFC North.While awaiting word on Long, Nagy said they were working on contingency plans for this weekend’s trip to Buffalo. Eric Kush and Bryan Witzmann are two possibilities to step in at right guard.Kush missed the win over New York with a neck injury, but is expected to play against the Bills. Witzmann signed with Chicago three weeks ago and made 13 starts for Kansas City last season while Nagy was the offensive coordinator for the Chiefs.Star linebacker Khalil Mack and wide receiver Allen Robinson also could return this weekend. Mack, who has five sacks and four forced fumbles in his first season with the Bears, sat out against the Jets with a right ankle injury, missing a game for the first time since Oakland drafted him with the fifth overall pick in 2014.“I’m hoping this week it grows and it gets better https://www.thebearsfanshop.com/Adrian-Amos-Jersey , but I’m gonna stay cautious with it always and we together are always gonna talk through it,” Nagy said.Robinson has been hampered by a groin injury. He has 25 receptions for 285 yards and two touchdowns in six games after signing a $42 million, three-year contract with Chicago in free agency. It won’t necessarily be Chuck Pagano’s fault."Being who you thought we were since 2005!Log In or Sign UpLog InSign UpFanpostsFanshotsSectionsBearsOddsAboutMastheadCommunity GuidelinesStubHubMoreAll 322 blogs on Horizontal - WhiteFanposts Fanshots Sections Latest NewsThe Bears DenNotesXs and OsSuperfansFrom The Desk Of...The Bears Defense Will Probably Regress in 2019New,52commentsIt won’t necessarily be Chuck Pagano’s fault.CSTShareTweetShareShareThe Bears Defense Will Probably Regress in 2019Brian Spurlock-USA TODAY SportsThe success of the 2018 Chicago Bears was driven by a defense that was at the top of the NFL. Exactly where they ranked depends on which metric you prefer, but Football Outsiders ranked them first overall, first against the pass, and second against the rush. That seems about right. In a perfect world, the Bears would ride the best defense in the NFL into the history books, remaining at the top of the NFC North for years. This would allow Matt Nagy the chance to develop Mitchell Trubisky and the offense, and all would be well.It’s probably not going to happen. The defense is likely to see a dip in performance, and that’s even assuming that they don’t lose any important players like Adrian Amos or Bryce Callahan. When that happens, some fans are likely to blame the loss of Vic Fangio and the introduction of Chuck Pagano. The thing is, it won’t be Pagano’s fault, necessarily, either.Defenses are really inconsistent on a year-to-year basis. This is a major reason it makes more sense for a team to invest in offense, and it’s also one of the reasons why the Bears are fortunate in having an offensive coach at the center of their organization.Turnovers Aren’t SustainableFootball Outsiders tells us that predicting turnovers is a difficult thing. In fact, it’s really unlikely for a team to sustain turnovers on a year-to-year basis. In 2004,it was noted that teams rarely sustain a presence at the top of the turnover board from one season to the next Jordan Howard Color Rush Jersey , and that exact same trend was found to be true again in 2014. For 2018, Chicago led the league with 36 takeaways. That is really, really good. It also does very little to suggest how the next season is going to go.To pick one finding out of many, 538 reports that from 2009-2018, a team’s interception rate in the prior season had only a 2.4% share of predicting the next season’s success. What Kyle Fuller did in 2018 was great, but there is little reason to think the Bears are going to stay at the top of the leaderboard in this regard.What this means is that Chicago’s defense--which had five more takeaways than the next-closest competitor in 2018--is unlikely to stay that dominant. This won’t be Pagano’s fault, even if fans look to find a way to blame him.Chicago Over-performed in SacksUnlike interceptions, quarterback hits do tend to be consistent on a year-to-year basis. Sacks, however, do not (and sacks only own a 3.6% share of predicting the next season’s success rate). Chicago was 8th in quarterback hits last season, with 95; that should have resulted in an expected sack rate of around 41 or 42 sacks. Instead, the Bears enjoyed 49 sacks. In other words, while quarterback hits are consistent, sacks are not. We should expect to see the same defense get slightly fewer sacks next season even if they do maintain the same rate of hitting the quarterback. That means that Chicago will likely field a top-half or even top-third defense. It does not suggest that they will be one of the very top teams in sacks, like they were in 2018.Defense as a Whole is VolatileIn general, defense is less reliable than offense. That’s one reason why offensive DVOA does roughly twice as good of a job of predicting the next season’s success as defensive DVOA. The top three defenses in 2016 were Denver, New York (Giants), and Arizona. In 2017 Eddie Jackson Jersey , those same units ranked 10th, 18th, and 4th. In 2018, there were--in the same order--5th, 24th, and 17th. A number of factors impact defense, including rules that are slanted to favor offenses and the ability of offenses to isolate aspects of a defense that they choose to focus on. In simple terms, an offense can almost always choose who gets to be in on a play, even if that choice is filtered through the opportunities provided by a defense. On the other hand, a defense cannot be guaranteed that its best players will even have a chance to make a play on the ball. Ultimately, what this means is that when the defense of the 2019 Chicago Bears take the field, they will likely be a capable unit. They will probably be able to take over games and win a few contests almost on their own. However, it is really unlikely they will dominate games as they did in 2018, and their struggles will have a number of explanations unconnected to either Vic Fangio’s departure or Chuck Pagano’s arrival as his replacement.
