CHICAGO -- The Chicago Bears' defense so thoroughly dominated the Los Angeles Rams on Sunday night in their 15-6 win that quarterback Mitchell Trubisky’s shaky three-interception performance barely registered.

Trubisky, 24, who missed two weeks because of an injury to his throwing shoulder, struggled with accuracy on several occasions Sunday night. He airmailed a pair of balls that the Rams intercepted, and he also underthrew a pass intended for Taylor Gabriel that Los Angeles picked off right before halftime. He finished the game 16-of-30 for 110 yards, one touchdown, three interceptions and a quarterback rating of 33.3 -- the lowest single-game passer rating of Trubisky’s career.

“When you look at it numbers-wise, I think there were some throws -- some of the interceptions sailed on him a little bit,” Bears head coach Matt Nagy said. “It wasn’t his best game. You know what I told him, I said, ‘who cares.’ I mean, we’re about winning games.

“He knows that we can all play better. It’s not all on him. So he’s going to get better from it.”

Trubisky insisted that his right shoulder did not bother him Sunday night.

“It sucked being out for two weeks,” Trubisky said. “But, I mean, the shoulder really wasn’t bothering me at all, not my mindset or anything like that.

“Yeah, I’m pretty disappointed in myself, that way I played … but it’s hard to be down when you get such a big win like that. You have to put your own selfish thoughts about how you played aside.”

Prior to Week 13, Trubisky’s had an overall passer rating of 97.7 in 2018.

“I mean, I’ll get everything corrected,” Trubisky said.

The Bears can take solace in the fact that despite Trubisky’s issues in the passing game, Jordan Howard rushed for a season-high 101 yards on 19 carries. And as rough as Trubisky played in the passing game, he made some good plays with his legs and, overall, the Bears' rushing game kept the usually high-powered Rams offense on the sideline. As a result, Howard and Co. kept the ball for 13 minutes longer than the Rams.

“They were playing really soft defense, taking away some of our downfield throws," Trubisky said. "We spread them out a little bit. I think the offensive line did a great job opening up holes for Jordan.

“He made up his mind tonight that when he touched the ball, he was going to run hard and finish runs and pick up tough yards for this offense. I’m very proud of him and the offensive line and how they were able to be a big part of this win tonight.”
