This marks an important phase in the development of the 24-year-old Trubisky, who's entering his third NFL season and second working under Nagy's direction. This system that's built to Trubisky's strengths and abilities is becoming second nature.
Now, Trubisky is working as an extension of Nagy in leading the Bears' offense.
"Ultimately I’m the guy out there," Trubisky said. "So we want the play to work how I see and how coach Nagy sees it. So everybody’s on the same page and I’m able to talk to guys in a way where I can teach it to them, they understand it and it just helps everyone get on the same page. When I know something I can explain it and make sure everyone’s going toward the same goal and executing the same play."
The differences in Trubisky are clear to his teammates and coaches -- and are something Nagy expects fans will see when the Bears take the field beginning in training camp. What has changed?
Trubisky is no longer just controlling what his offense does, but he also can anticipate what a defense will present and how it can be beat.
Bears offensive coordinator Mark Helfrich can sense the growth of Trubisky when a play is called in to him. Processing it all quickly, Trubisky can now communicate with ease to the huddle. If a defense presents something different, Trubisky is often changing the play as Nagy and Helfrich would like.
"The air about him, it's way different," Helfrich said. "And everybody has noted that."
Trubisky showcased growth as he worked in a new offensive system in 2018, helping lead the Bears to a 12-4 record and the NFC North crown. But the offense left more to be desired, averaging just 343.9 yards per game, 21st in the league.
With another year together, the Bears offense envisions better in 2019, but it will take better play from Trubisky to take that step forward.
Trubisky's teammates see his progress.
"The biggest thing now is he really wants to dissect a defense," receiver Allen Robinson said. "That's really the biggest thing. We're in this mode where we want to make plays. We're not just getting ourselves into just completions or running plays to be running. We're really trying to attack the defense and really beat the defense every single play."
For Trubisky, hearing of the praise that he has received is yet another driving force for his offseason. He knows the Bears are counting on him.
"I mean, the ultimate compliment is just the respect you can get from your teammates," Trubisky said. "That’s the reason you play the game. That’s the reason you work hard to earn the respect of your peers and your teammates, because those are the guys who you lay it on the line for every single Sunday. That’s exactly what we’re trying to do."
