This offseason has been different for Bears quarterback Mitch Trubisky, and his teammates have taken notice.

The Bears went 12-4 and made the playoffs in his first full year as the team's starting quarterback, but the third-year pro still has plenty of room for growth within coach Matt Nagy's offense.

The experience and success from last season is expected to fuel that growth, both in Trubisky and the offensive unit as a whole, Trubisky's drive and focus have been the biggest catalyst for positive change.

Amid high expectations, Trubisky was pleased with the progress he has made in the offseason program.

I’ve got a lot better grasp of the offense,” he said. “We’re way ahead as far as timing, operation, getting to the line of scrimmage, getting in and out, adjustment on all of our plays and just knowing where to go with the football.”

Those around him have noticed the difference.

“It’s confidence,” wide receiver Taylor Gabriel said. “Mitch is confident back there. He’s confident in switching the calls. We’ve got a lot of double moves out there. It's a drastic change from last year.”

The offense was often the weak link last season, despite it being much improved from the mundane stuff the team ran two years ago.

Nagy brought the Andy Reid system from the Kansas City Chiefs to Chicago, and the creative nature of Nagy's playbook sometimes covered up for Trubisky, who started just one full season in college.

Overall, Trubisky's sophomore season was a success. But he'll need to be much better if the team is to make a deep playoff run this year.
