Well there was good and bad from that Bears first half. The good was how good the defense looked for a good chunk of that first half. They're the main reason this game is so close. The bad was how the offense looked. Quite a stark difference from how they looked late last season.
And that sack is the cherry on top of an absolute dud of a performance from the Bears offense tonight. While Bears have had seasons in past where D has carried them in spite of the offense, there's way too much talent on this offense to have a performance like this one.
But I will defend Trubisky a little. He threw it 45 times tonight. We only ran the ball 15 times. That's ridiculous. Jam it down their throat and pick and choose when to sling it. That's how Trubisky will be successful IMO. 3 capable RBs and we use them as WRs most of the time.
