Mitchell Trubisky spiked the ball and let out a scream.
In a divisional matchup of Bears and Lions, this Bears' primal growl roared the loudest.
And why not shout?
The second-year Bears quarterback had just capped off a brief four-play, 18-yard drive with a run up the gut of the Lions defense and into the end zone.
Chicago went up 26-0 and Trubisky was headed toward his second first-half of the season with a perfect 158.3 passer rating and the Bears were on their way to a 34-22 win.
Trubisky could do no wrong on Sunday.
"It'd probably be one of my best games, just felt really comfortable out there," Trubisky said. "It was just me doing my job, sitting back there getting the ball to the playmakers, so I just felt really comfortable today, and I put the ball where it needed to go, and it's all credit to my teammates."
He wasted no time against the Lions getting reacquainted with receiver Allen Robinson II who had missed the last two games with a groin injury. On the first drive of the game, Trubisky hit Robinson cutting across the middle of the field for his first reception since Oct. 21. Robinson broke a tackle and jetted ahead for a 35 yard pickup to set the Bears up for their first score.
After the Bears defense forced the Lions to punt, Trubisky and company got right back to work on their second series.
After a few run plays didn't net much, the Bears looked to attack through the air again. Chicago went into a no-huddle hurry-up setup on a second-and-eight play and Trubisky found Robinson again, this time down the right sideline for a 27 yard gain. Four plays later, it was déjà vu with Trubisky laying a perfect back-shoulder ball into Robinson's hands in the right corner of the end zone to put the Bears up 13-0.
"He made a huge impact," Trubisky said of having Robinson back. "He's just so hard to cover one on one. He's just another dynamic weapon for this offense and another guy to account for, so I'm going to continue to look for him."
Having Robinson back added a new versatility to the Bears offense that had been missing over the last two weeks, and Trubisky was able to get everyone involved, targeting seven different players on the day.
After the Trubisky-Robinson connection, Trubisky came out firing again. He hit running back Tarik Cohen in the open field for a first down pickup in the Bears' third drive, and fired a bullet to tight end Trey Burton for a short gain later in the series. On the next play, from the Detroit 45 yard line, Trubisky found receiver Anthony Miller wide open 20 yards from the line of scrimmage. Miller made the catch, broke a tackle and had a clear path for a score.
Trubisky credited some of the early offensive explosiveness to the Bears' fast pace this week. The Bears ran a no huddle setup nine times on Sunday.
"We had a nice little no huddle package today," Trubisky said. "We were just playing fast, think it plays well into my skill set, and something I'm comfortable with."
Chicago was up three scores in its second divisional game of the season and Trubisky wasn't even close to slowing down.
On the Bears' fourth drive of the half, Trubisky showcased what makes him so dangerous — his ability to adapt, adjust and tuck the ball and run when needed.
After a second-and-10 play fell apart, Trubisky scrambled to his left, then back to his right for a six yard pick up. Less than two minutes later, Trubisky went up the middle for a rushing touchdown — one of three carries he had for 18 yards on the day.
In the second half it was more of the same. Trubisky used two plays in the third quarter to move the Bears 50 yards for their fifth touchdown of the day by way of a Burton 24-yard pickup and another Trubisky-Robinson hook up for 26 yards and a score.
The Lions rallied for two touchdowns in the fourth, but with the way Trubisky was playing, at no point did it ever feel close.
Trubisky finished with 23 completions, a career-high 355 passing yards and four total touchdowns.
It was the type of performance that will keep many who have been critical of the young quarterback quiet for a while — not that any of that criticism bothers Trubisky.
"People are talking on the outside, but I don't even hear it," Trubisky said. "I'm just going to go about my business, do my job and my love for my teammates grows even stronger that way, and I just want to play that much better and play the way I know how, because I know those guys in the locker room and my head coach and all my coaches got my back."
