Trubisky isn't there yet.
The Bears' entire offense, not just Trubisky, had a forgettable performance in Saturday's 20-10 loss in Detroit, but quarterback play is always magnified -- for better or worse.
Trubisky committed the cardinal sin of turning the ball over in bunches at Ford Field. That opens any quarterback up to scrutiny. Trubisky finished the game with three interceptions, but the most costly occurred on a third-and-goal play when Trubisky forced a ball to wide receiver Dontrelle Inman that Detroit safety Quandre Diggs picked off in the back of the end zone.
It's a throw Trubisky simply can't make.
"I lost [Diggs] in my vision," Trubisky said. "I should've thrown the ball away and settled for the field goal."
That mistake was all on Trubisky, but the overall sloppiness on offense made it difficult for any Bear to thrive.
The Bears were flagged 13 times for 97 yards as a team, but on one drive in the fourth quarter, the offense committed five separate infractions. The fact that drive actually ended with a touchdown -- Trubisky to Benny Cunningham for 9 yards -- was nothing short of a miracle.
"We got to eliminate penalties and then me taking care of the football, so we just need to do better at those things," Trubisky said. "Take care of the ball in red zone, be better on third down, obviously, and just execute better on offense all the way around. So last week we had a little juice, executed, had things rolling. [Saturday], it seemed like the opposite, so just got to go back, be critical on film to see what I can get better at and continue to push my teammates to get better.
"Everyone's just got to make a conscious effort to say we're not going to make penalties anymore. We're going to play clean football and, I don’t know, what am I going to say to my guys for holding? I mean, they're blocking for me. So I can never say anything to my linemen because they're out there protecting me and I love that. So the effort's there, we just got to keep playing technical."
All the extenuating circumstances made it easy for the Bears to shrug off Trubisky's up-and-down Week 15.
"I've been super, super impressed, his growth, his production as we've gone," Bears coach John Fox said. "I haven't watched the tape yet; it's going to be hard to say. You look at the box score, and people talk about the three picks, but I don't know exactly what happened on all of them. A couple of them appeared to be overthrows, but we need to go back and look at it in the film room. I've loved how he's grown and matured, and even today with his screen pass. You know, he spiked it in the dirt. He's had steady growth. I think he's improving every week."
Added wide receiver Kendall Wright: "If I know Mitch, when he goes up there and does his media thing he'll take all the blame and say it's all his fault. It's not all his fault, man. Mitch is fine. Mitch is fine."
Enough evidence exists to suggest Trubisky will, in fact, be fine.
It's just going to take longer than some would like.
