Maybe you saw the first offensive play the Bears ran in the Matt Nagy era Sunday night. Three running backs in the backfield. Michael Burton next to Tarik Cohen next to Jordan Howard. Yes, that was indeed the T Formation, Nagy's subtle homage to the history of the NFL's charter franchise.
And maybe you drew belief from the first series the Bears put together against the rival Packers at Lambeau Field. Eighty-six yards in 10 plays, capped with quarterback Mitch Trubisky plunging into the end zone for an early touchdown.
And maybe you watched the next Bears possession as well. Another long march. A beautiful deep ball from Trubisky to Allen Robinson for 33 yards. Another scoring drive, this one ending with a Cody Parkey field goal.
Man, this looked different. This offense looked fun. This looked like a young Bears team understanding its potential, like a group looking to chase the biggest of dreams that a hopeful football city has envisioned for it.
What could be better than a 20-point lead over the Packers? On the road. In the second half.
So how in the world did the Bears finish Sunday night describing another rough loss, a 24-23 gutting by Aaron Rodgers and Co.?
How were Nagy and Trubisky left not in a victory lap but offering details of the wreck, like drivers in a car accident left to tell the police how their vehicles had wound up wrapped around the street light.
"We had a little lull there," Nagy said. "(In the second half), we had two three-and-outs and then they had two touchdowns. I think that's where you can start seeing that things were going the other way."
Maybe, in one September prime-time snapshot, we saw the 2018 Bears for everything they will be over the next 16 weeks. This was a team that delivered flashes of obvious promise. This was a team doing so many things on a higher level than they have done in the past three or four years. This was a team with an intriguing cast of potential playmakers. And ultimately, this was a team still figuring out how to make bigger plays in big moments of big games, a team still climbing toward the prominence the Packers have known for years.
The second half damage? Rodgers: 273 passing yards; Trubisky with 62.
The reality check? After cruising for a touchdown on that opening series, the Bears offense had nine more possessions and never reached the end zone again.
Said Trubisky: "In order to be a good quarterback in this league, red zone and third down is where you make your money. I wasn't good in those areas tonight."
Trubisky's combined numbers on third down and in the red zone -- 10-for-15, 57 yards -- weren't damning but certainly could use improvement. And all those third-down missteps in the second half came back to bite the Bears.
There was the third-and-11 Trubisky scramble that came up 2 yards short of the sticks. The third-and-2 pass to Anthony Miller on the Bears' final field goal drive that fell incomplete. And yes, that odd third-and-1 play-action pass in which Trubisky rolled right, then threw back across the field to Dion Sims for no gain.
"That was a built-in play," Trubisky explained. "And that was pretty much my only option. It was built for man (coverage) and they were playing zone. That's just one of those risks you take. If we get the right look, it's wide open and we look like geniuses. But they just made a play."
Of all the brutal losses this organization has experienced at Lambeau Field in recent years, Sunday night's carried a different sting. For once this wasn't an obviously inferior team being exposed as such. It was a team that should have scored one of the most head-turning upsets of Week 1 in the NFL but didn't.
"We're a young team that is going to learn from these situations," Nagy promised. "And so I told them, you can feel tonight. That's OK. It's OK to feel tonight. Feel bad. Be pissed. All that. But once we get back tomorrow, we learn from it."
There's another thing different about this loss to the Packers as well. It was the season opener, 15 still games behind it. And that as much as anything should give Trubisky and his offense motivation. To keep plugging. To keep learning. To keep learning the details of a Nagy system that should become more exciting and more productive as the season moves along.
Asked about that opening touchdown drive, Nagy lit up.
"I knew we could do that. I really did," he said. "And they proved it. It was so good for our guys to have that. They didn't get a whole lot of reps in the preseason. So for them to see what can happen (was good). Some of those plays were scripted. So they're able to study them. But they see it's there. They understand that it's there."
Added Trubisky: "We were in attack mode."
Receiver Taylor Gabriel felt the energy of that TD march.
"It just shows that our preparation of what we've been doing finally came to fruition," he said.
So why didn't the marches continue? For one thing, Trubisky said, the Packers adjusted and used a lot more zone coverage than the Bears were expecting.
Nagy dismissed the idea that he took his foot off the gas with the big lead, a topic that will be scrutinized for the next week after the Bears ran 38 second-half plays Sunday night and gained more than 10 yards just four times.
With the Packers playing more zone and backing off in coverage, the rookie coach felt more than comfortable leaning on a running attack that averaged 5.1 yards per carry for the night.
Still, as time goes on, this Bears offense will have to learn how to go in for the kill.
Trubisky's numbers in the second half: 3.0 yards per attempt, only two completions longer than 10 yards, and none longer than 12.
The second-year quarterback was appropriately deflated. He was also appropriately hopeful.
"We're close," Trubisky said. "We know how close we are. ... We're headed in the right direction."
Maybe Sunday night's final result was a fitting measure of this group's progress. Maybe that 3-hour roller coaster, of anticipation and adrenaline and excitement and dizziness and disappointment, provided updated evidence that this is not a team on the verge of stunning the entire NFC.
Maybe it's a team that's still approaching the verge before the verge. If the Bears aren't close, they're certainly closer. For now, that's what they will live with and build off.
