Sunday, the Bears got a more relaxed Justin Fields. How did he stay calm?

It's probably impossible to put into words just how much mayhem occurs during an NFL game.

And that goes double - maybe even triple - for a team's quarterback.

Get the play call right. Make sure everyone hears it. Make adjustments at the line. Take the snap and execute as complete chaos unfolds around you.

Now do it again.

And again. And again.

Some guys make it look so easy, while others wilt - and are constantly sacked - under the pressure.

For QB Justin Fields, something seemed to click a bit during the Bears' 29-22 loss to Minnesota on Sunday.

Now, we're not suggesting Fields will suddenly rocket to Lamar Jackson/Patrick Mahomes status. But he looked awfully impressive on the Bears' last five drives, going 13-for-15 for 174 yards and also running 4 times for 24 more yards.

"He kept the team together," Bears offensive coordinator Luke Getsy said.

So what was it? Why was Fields so poised?

Apparently, some credit goes to a yoga instructor the Bears brought in to help players with their breathing in-between plays.

"It just allows you to stay calm," Fields said. "I just kind of try to work on my breathing as much as I can."

While he did this at times in Week 4 vs. the Giants, Fields said he really put it into practice against the Vikings.

"Like after the long (52-yard) run, (I came) back and just slowed my breathing down," Fields said. "I feel like I don't get as tired in the game, too. It definitely has a lot of benefits for sure."

Fields is also getting more comfortable in his own skin.

Everyone else is acting crazy? No need to join them.

Chill out and be yourself.

"Last year sometimes I felt like I had to speed up myself or just be crazy (and) pumped up because everybody else is," Fields said. "But I think playing quarterback, the more you can stay calm (and) the more you can stay relaxed the better you'll play.

"(It) allows my teammates to stay calm ... in situations that are big. Just act like you've been there before."

There's no better example of this than when 49ers quarterback Joe Montana - with Super Bowl XXIII on the line - looked at right tackle Harris Barton and said, "Hey, H. Look down there in the other end zone. There's John Candy!"

Montana, who knew how uptight and nervous Barton was, did this during a TV timeout with just 3:20 remaining and the Niners trailing the Bengals 16-13. Montana then led San Francisco on a 92-yard drive to win the game.

"It's typical Joe," Jennifer Montana said in an NFL Films video, "just to take everybody's mind - and especially Harris' - off the importance of that drive just to remind him, 'This is a game. Let's go have some fun."

A more relaxed Fields, who threw for more than 200 yards for the first time Sunday, was trying to lead the Bears to a last-minute, game-tying drive against Minnesota. He was sacked for an 11-yard loss on the third play, but rebounded by connecting with Montgomery for 21 yards on second-and-21.

Then Fields hit Ihmir Smith-Marsette for 15 yards, but Smith-Marsette had the ball stripped and the game was over.

Despite the unfortunate ending, Fields' progress - while not monumental - was nonetheless apparent.

Now we'll see if he can carry it forward to Thursday's game against Washington. Montgomery has no doubt it will happen.

"He's bringing this aura to have everyone behind him, following, to the way he plays," Montgomery said. "His poise, how calm he is. If your quarterback can be calm in hostile situations, I have no other choice but to be calm because he's the one calling shots.

"So if he's out there calm and he's chilling, I've got to be the same way. I can't flinch if he ain't flinching."
