Bears quarterback Mitch Trubisky will be one of the first ones to tell you the team's offense was average at best, at times, during Matt Nagy's first season in the Windy City.

The Bears are counting on two elements, in particular, to improve that in 2019: their retooled backfield and players’ experience in Nagy’s system. Aside from Tarik Cohen, the Bears have also added Mike Davis and rookie David Montgomery.

Trubisky senses momentum behind both.

“We’ve got a three-headed monster that’s going to be able to make huge plays for this offense,” Trubisky said per Rich Campbell of the Chicago Tribune . “Very talented guys and pretty much handpicked by (general manager) Ryan Pace and Coach Nagy. I 100 percent believe in those guys.

“Just being around Mike and being back with Tarik, you just feel like these guys really fit this offense and are able to do the things we want them to do — running the zone scheme, making guys miss, extending plays, running guys over and catching the ball out of the backfield. That’s what we expect from David and Mike.”

The Bears ranked 27th in the NFL in yards per carry, 20th in yards per play and 21st in total offense during Trubisky and Nagy's first year together. Those disappointments ended up outweighing encouraging areas of production, such as red-zone efficiency (tied for sixth), third-down conversion rate (11th) and time of possession (third).

Trubisky acknowledged the expectation that Year 2 in Nagy’s scheme will naturally be better.

“We have that experience but also that humbleness to work hard and want to correct our mistakes,” he said. “When you see the flashes from last year, that’s what excites you. But we’re humble enough to be like, OK, when it didn’t go so well, this is what we need to work on.”
