to keep Khalil Mack out of their backfield."We had about four guys blocking him Pat O'Donnell Jersey ," Miami coach Adam Gase said.But what happened to the rest of the Chicago Bears' defense? A unit stirring memories of the Bears' glory days gave up 541 yards Sunday in a 31-28 overtime loss.And Miami played without quarterback Ryan Tannehill, inactive because of an injury to his throwing shoulder. Replacement Brock Osweiler threw for a career-high 380 yards .Four Miami plays gained more than 30 yards, including catch-and-run touchdowns covering 43 and 75 yards by Albert Wilson. The breakdowns were surprising from a defense that allowed only 65 points in the first four games this year."Can't give up too many big plays for what we're capable of on defense," Mack said.The two-time All-Pro linebacker was especially quiet with two tackles. Mack suffered an ankle injury early in the game and briefly went to the sideline, and his 2018 streak of at least one sack and one forced fumble in every game came to an end.The Bears (3-2), who were averaging 4陆 sacks per game, totaled none even though Osweiler threw 44 times. Defensive tackle Akiem Hicks found it difficult to evaluate the pass rush."We didn't get any sacks," he said. "You can't assess it when you don't get any sacks."Run defense was no better. Frank Gore http://www.thebearslockerroom.com/authentic-kyle-long-jersey , the Dolphins' ageless 35-year-old running back, gained 101 yards in 15 carries. Teammate Kenyan Drake added 57 yards."It all starts with stopping the run," Mack said, "and we didn't do a good job with that today."The fourth quarter was again a problem for the defense, which failed to protect a 21-10 lead with 16 minutes left. Of the 96 points allowed this season by the Bears, 60 have come after the third quarter.Miami had 387 yards after halftime. A sunny, 90-degree afternoon might have been a factor in the Bears' fade, both on offense and defense.Guard Kyle Long Womens Tom Waddle Jersey , for one, hadn't read the forecast."It was a shocker when we walked out of the locker room and it's 400 degrees in the shade," he said.But the defense made mistakes early in the game, too. Linebacker Leonard Floyd was called for unnecessary roughness when he body-slammed receiver Danny Amendola , which led to the only touchdown in the first half."He was trying to gain more yards," Floyd said, "and I was trying to stop him."Coach Matt Nagy declined to discuss Floyd's play. Otherwise, Nagy preferred to praise the Dolphins rather than criticize his defense."You have got to give credit to them for playing a good game Sam Acho Jersey ," Nagy said. "They made plays." The Bears opened up space alongside Tarik Cohen in their backfield by trading Jordan Howard this offseason and third-round pick David Montgomery joins free agent acquisition Mike Davis as the likeliest candidates to fill it.Early signs about the rookie’s chances of doing that have been positive. Montgomery’s skills in the passing game got a thumbs up from head coach Matt Nagy and running backs coach Charles London said his ability as a runner was also evident right off the bat.London said Montgomery has “pretty rare contact balance,” which gives him the chance to gain yards even when there’s a lot of traffic ahead of him on the field.“He definitely possesses that,” London said, via Adam Jahns of TheAthletic.com. “It’s important from the running back position because every play is not going to be clean and every hole is not going to be clean. Sometimes you just got to create that on your own. He did quite a bit of that at Iowa State. That was something that we noticed. And that is something you really can’t coach. You either kind of got it or you don’t and he does. It’s something we quickly noticed about him.”London said Montgomery was focused on learning the offense and his role this spring, but that he can see the running back taking on a leadership role as time goes on. If the offseason praise turns into regular season results, that may happen sooner rather than later.
