Like a flower, the Bears' new offense needs some time to blossom.

First-year coach Matt Nagy once again preached patience Wednesday with young quarterback Mitchell Trubisky and a scheme that's still in its infancy in Chicago.

"He's doing well," Nagy said of the 2017 first-round draft pick. "He's where I thought he would be at. What I'm doing now is understanding what the plays are that he's doing well with."

In the Bears' first three games of the season, Trubisky has completed 69.2 percent of his passes (72 of 104) for 591 yards with two touchdowns, three interceptions and a 77.8 passer rating. He has also rushed for 64 yards and one TD on 14 attempts.

In studying Trubisky and the rest of the offense, Nagy is discovering that the most and least successful plays the Chiefs ran when he was an assistant in Kansas City the previous five years aren't necessarily the same with the Bears.  

"What's neat is that there are concepts that weren't as good to us in Kansas City that are good here, that are working," Nagy said. "I'm learning that and now those are the ones I'm going to start to go to because I see that. And vice versa. There's some that we did well in Kansas City that might not be as efficient now."

Having quarterbacked the Bears' new offense for only three games, Trubisky understands that the unit remains a work in progress that will continue to grow.

"We're still trying to figure out all the ins and outs of the offense and what our identity is going to be as a team and as an offense," Trubisky said. "We're just continuing to go through all the concepts … and figure out what fits us best, what we're really good at, what we still need to work on and what our go-to plays are.

"We're working out the kinks and we're just going to keep grinding; working hard in practice and trying to put a good product on the field. But it all comes down to execution and everyone being on the same page and playing fast."

Nagy knows that the key to playing fast is not overloading Trubisky or his teammates with too much information.

"We can't put him in a situation where we're trying to do too much and we take away from their talents, our players, all of them, not just the quarterback," Nagy said. "If we're doing too much, making him think too much, they're going to play slow and they're not going to be efficient.

"What we get paid to do as coaches is to know what that balance is, and then we need feedback from the guys, and as long as we feel like the feedback is good and they're OK, then we'll continue doing what we're doing. But it's about production and you have to produce and you have to score points and if you're not producing or you're not scoring points you've got to dig into the why part."

The Bears are focused this week on improving their red-zone efficiency after scoring only one touchdown on three trips inside the 20 in last Sunday's 16-14 win over the Cardinals.

"We know right now offensively that we're not where we want to be," Nagy said. "We're not in any type of panic mode because we understand that part of the process, but we're going to do everything we can to try to get better."

Nagy acknowledged that Trubisky has a lot on his plate, but the Bears coach doesn't think the second-year quarterback is thinking too much.

"If he was thinking too much, then he wouldn't be taking some of these shots [down the field], he wouldn't be getting in and out of the huddle, he wouldn't be making the right ID calls with protections," Nagy said. "It's more him just getting some more reps at some of these plays, and then us and him collaborating as to which plays do we feel most comfortable with."
