y ticket: 12-80-10.The Chicago Bears coach is hoping the offense can strike it rich this season with the additions of receiver Allen Robinson (No. 12) and tight end Trey Burton (No. 8) www.chicagobearsteamonline.com , to pair with young quarterback Mitchell Trubisky (No. 10).Throughout camp, the trio has steadily honed their chemistry. That was evident Thursday when the team had a joint practice against the Denver Broncos."The one thing I've really seen is 12 and 80, both their timing is starting to click with 10 ," said Nagy, whose team faces the Broncos on Saturday in a preseason contest.Robinson is rounding back into form after tearing his ACL in the opener last season while with the Jacksonville Jaguars. He signed a three-year, $42 million free agent deal with the Bears to become Trubisky's top target.Then there's Burton, a member of the Philadelphia Eagles last season who may be best remembered for throwing a 1-yard TD pass to quarterback Nick Foles during a Super Bowl win over New England.Burton rattled off numerous reasons why he signed with Chicago — the offense, the coach, the city and of course No. 10."A young quarterback who everybody says nothing but great things about," Burton said.The second-overall pick in 2017, Trubisky threw for 2,193 yards, seven TDs and seven interceptions his rookie season. With Nagy running the show, the Bears figure to take more shots down the field.That's extremely enticing to Trubisky, whose team ranked at the bottom of the league in yards passing per game in 2017."We're going to keep being aggressive," Trubisky said. "The key is to be consistent with them, hit them. It really stretches the field, and it opens up the run game Chicago Bears T-Shirt , opens up the intermediate throws as well. We're going to continue to be aggressive, which I love."Asked what he does best on the field, Trubisky didn't blink: "That's too generic."He quickly pondered."What do I think I do best? I don't know. I love football," he responded. "I love coming out here with my teammates and doing the best I possibly can. I wouldn't say there's really one (way) how I would categorize my game. I want to continue to get better every day and try to be great."Maybe a little surprising is how fast Trubisky has gotten in sync with Robinson and Burton."It speaks to the type of guys they are, their knowledge of the game and their work ethic, as well as mine," Trubisky said. "We've been getting on the same page, repping over and over again and really developing that trust and chemistry on and off the field so I know where they're going to be. They do a good job getting open. We've really been clicking."Robinson is slated to see some action for the Bears on Saturday. Trubisky and the first-team offense gained minus-1 yards on eight plays last week at Cincinnati.Obviously, Nagy wants to see more."You want to score touchdowns. You want to be able to put points on the board," Nagy said. "I want to see some first downs. I want to see a balance of run and pass. I want to see solid protection. If you have protection and give that quarterback green grass, they'll produce."Nagy liked what he saw out of Trubisky after two days of facing a Broncos defense featuring the disruptive Von Miller."Arrow up," Nagy said. "It was two good days and that's what his expectations are and that's what he knows we want."He does at that."Every snap matters. Every practice rep, every preseason game matters," Trubisky said. "We're coming out here competing every day. We're always trying to get better. No matter what it is, if it's on the practice field, if I'm in the backyard by myself or if it's a preseason game, we're trying to get better and we're trying to move the football."That's what great players do. That's what great teams do. We're trying to get some momentum."One dark-horse candidate at each Bears defensive position who could move up the depth chart Unlike their offense, the Chicago Bears will be returning most of their defensive starters from the 2017 season. A few additions were made - most notably first-round pick Roquan Smith - but the core from last year’s roster was able to stay in tact.Although the starting lineup will remain similar Chicago Bears Hats , there are a handful of intriguing new players coming off of the bench who could be fighting with free agent signings and returning veterans for playing time. As a follow-up to Thursday’s article, let's take a look at one Bears player at each defensive position who could end up climbing the depth chart by the time the regular season rolls around.Defensive lineInstead of Jonathan Bullard: Roy Robertson-HarrisArguably the only true starting battle on the roster, the defensive end spot is currently up for grabs. Akiem Hicks has one of the spots locked in, but Jonathan Bullard or Roy Robertson-Harris will have to fight it out to secure a starting role.Bullard, a 2016 third-round pick, currently holds the starting spot by a narrow margin, but the Bears may actually be better off starting Robertson-Harris, who flashed potential in limited playing time last season. Both hold up a valid argument to be added to the starting lineup, but Robertson-Harris has the physical tools of an NFL starter.Reasons to love Robertson-Harris: Robertson-Harris has an intimidating blend of size and speed that a lot of 3-4 defensive ends wish that they could have. The six-foot-seven, 294-pound UTEP alumnus played edge rusher in college and ran a 4.84 40-yard dash at his Pro Day in 2016, and hasn’t seemed to have lost much of that explosiveness since transitioning into an interior defensive lineman. Edge rusherInstead of Aaron Lynch: Kylie FittsHere’s something you probably haven’t heard at all this offseason: the Bears are thin at the outside linebacker position.In an offseason full of impressive moves and noteworthy shakeups, Chicago’s group of edge rushers was barely improved, if at all. At the end of the day, though, they’re going to have to make due with what they have, so they might as well give more playing time to players with upside.Aaron Lynch was signed in hopes that he could replicate his 2015 form, but that seems highly unlikely after two straight seasons that were plagued with injury and less-than-stellar performances. The Bears would be better off giving more playing time to Fitts, who himself has had injury issues over the past two years Chicago Bears Hoodie , but has more potential to tap into than Lynch.Reasons to love Fitts: Fitts is a well-rounded edge prospect who offers a bit of everything. He’s a solid athlete with good first-step acceleration who can also shed blocks well on a consistent basis. He isn’t perfect, but he has the talent to be a long-term rotational edge rusher for the Bears.LinebackerNoneA position without any change! Gee willikers.The Bears’ organization at the linebacker position couldn’t be made better with the players they have on their roster. Danny Trevathan and, eventually, Roquan Smith make up a formidable starting duo on paper, with Nick Kwiatkoski as the primary backup. The likes of Joel Iyiegbuniwe, Jonathan Anderson and John Timu are all aptly placed, as well.Defensive backInstead of Marcus Cooper: Kevin ToliverChicago seems to be relatively set for the most part at cornerback, with Kyle Fuller and Prince Amukamara secured as the starting outside corners and Bryce Callahan in the nickel. Players like Cre’Von LeBlanc and Sherrick McManis figure to be safe bets to make the 53-man roster, as well. Marcus Cooper can also be placed in that category, but he might be better off taking a back seat on the depth chart.Kevin Toliver, an undrafted free agent out of LSU, has been one of the most impressive rookies in training camp thus far, and he has a higher ceiling than most undrafted free agents. If he ends up making the team, then he could be a very good insurance option for one of the two outside starters.Reasons to like Toliver: Two words: physical tools. At six-foot-two and 192 pounds, Toliver has impressive length for a defensive back. He’s physical in man coverage, is a solid athlete and provides some value as a tackler.Jacob Infante is a Chicago Bears writer at SB Nation’s Windy City Gridiron.
