Mitch Trubisky did not need to be told he didn’t play well in Sunday night’s 15-6 victory over the Rams, and he won’t have to be told he needs to work hard this week to correct the mistakes that plagued his return from a shoulder injury.

So Bears coach Matt Nagy took a different tack after the game at Soldier Field when he addressed his quarterback, who finished with a season-worst 33.3 passer rating.

“It wasn’t his best game, but you know what?” Nagy said. “I told him, ‘Who cares?’ We’re about winning games. He knows we can all play better. It’s not all on him.

“These are the ones you look back for myself as a coach and him as a quarterback that you grow from. When you win the game, it’s a lot easier to critique and understand the ‘why’ part and use it to help you down the road. In the end, can we be better as an offense? Yes. Do I care about numbers? Not one bit.”

Trubisky’s return after he missed two games wasn’t triumphant.

He had his first three-interception game of the season and the second of his career. He completed just 16 of 30 passes for 110 yards and one touchdown.

Trubisky said it wasn’t the freezing temperatures that hindered him, and he added his shoulder felt fine. But he said he was “trying to do too much” on some plays.

That might have accounted for some of the inaccuracies that popped up. He threw interceptions in the first, second and third quarters, to Marcus Peters, Nickell Robey-Coleman and John Johnson III. He overthrew wide receiver Josh Bellamy and tight end Trey Burton on the first and third picks.

“I was pretty amped and anxious coming out for this game because I was out for two weeks,” Trubisky said.

“That had nothing to do with the way I played. I just need to settle down, be better with my footwork and try not to do too much. There were times I was just trying to do too much to make a play. I don’t know if that was something I was doing mentally from sitting out two weeks, just come out and put on a show and make big plays. I just need to go out there and do my job.”

The Bears showed they can win — and not just win but beat one of the best teams in the NFL — when Trubisky is not at his best.

Afterward, Trubisky was able to separate his mistakes from a huge victory for his team. He said he still danced in the “Club Dub” postgame locker room party. He still shared postgame hugs with his teammates.

“I’m pretty disappointed in myself with the way I played, especially being out two weeks,” Trubisky said. “It’s hard to be down when you get such a big win like that. You just have to put your own selfish thoughts, how you played aside, because that is selfish. …

“I’ll get everything corrected. I’m going to go back to work this week, work really hard to get it corrected and play a lot better. I’m just very proud of the way this team had my back.”

Nagy said Monday he didn’t think the outing was a step back in Trubisky’s big-picture development but said there’s plenty to work on, including how Trubisky reacts when he is presented with a defensive look they weren’t expecting.

He noted Trubisky came through on the Bears’ lone touchdown drive in the third quarter. On the nine-play, 81-yard drive, Trubisky completed 4 of 5 passes for 36 yards.

“They wanted to play a certain way, so we wanted to make sure we adjusted the right way,” Nagy said. “Getting into some of those RPOs was what we felt in that situation was the best thing for us and they were working.”

Trubisky’s lone touchdown pass came when the Bears put in four defensive linemen and no receivers or backs. He faked a handoff to defensive lineman Akiem Hicks, who scored an offensive touchdown last week. Trubisky then found offensive lineman Bradley Sowell in the end zone for a 2-yard touchdown pass.

The play was called “Santa’s Sleigh.”

“Santa’s Sleigh came a little early,” Trubisky said.

The Bears defense slipped a gift to Trubisky into the sleigh too.
