​ATLANTA — When Caleb Williams walked into Chicago Bears coach Ben Johnson’s office earlier this week, the quarterback kept it brief.“I walked in his office, dapped him up and said let’s get this thing going this week,” Williams said. “I walked out after that.”That was all Johnson needed to know his quarterback was ready. Well, besides the go-ahead from the medical staff, which did come after a week of full participation in practice. But from the mindset side of things, Williams was ready to roll.It showed Sunday in a 31-23 victory over the Atlanta Falcons at Mercedes-Benz Stadium. Williams completed his first 12 passes and finished 30-for-36 for 305 yards and a touchdown.Sunday marked Williams’ return after missing three games with a right hamstring injury that he described earlier in the week as a “pretty serious” tear. Williams was last seen writhing on the Soldier Field grass after he took off on a fourth-quarter run in a Week 2 loss to the Minnesota Vikings.If there were any remaining doubts about the health of his hamstring, Williams silenced them on the first possession Sunday.After the Bears received the game’s opening kickoff, Williams completed six passes in leading the offense on a 10-play, 67-yard scoring drive that overcame 20 penalty yards.“Just the leader, the commander, having him in the huddle is good, it’s good to feel,” tight end Colston Loveland said. “He’s got (an) elite-dog mindset and he’s doing anything to win.”On a second-and-long in the red zone, Williams scrambled to his right with what looked like full trust in his legs and zipped a pass between two defenders for Loveland in the end zone. It was Loveland’s first touchdown of the season.“Colston and I locked eyes and (I) just gave my guy a shot,” Williams said of the play.Williams was fired up celebrating with teammates after the touchdown. The franchise quarterback had never missed a game in his NFL career before this stretch. He had never missed a start due to injury in college either.“Obviously I was super juiced up trying to get back out here over the weeks,” Williams said. “Super juiced up to be back out here and I think it’s just completion, completion, completion. That’s the focus. That’s the mindset. I’ll be able to keep everybody cool, calm and collected, even myself. Then, other than that, give the guys a shot. Give them a good ball and then let them go make plays.”He may have been calm in the huddle, but he let his emotions show after the first touchdown. And he didn’t have to wait long for another chance to make plays.After a quick three-and-out from the Falcons offense, Williams again drove the Bears methodically downfield. On a third-and-17 on their end of the field, Williams connected with Rome Odunze for a 23-yard completion. Odunze extended his arms to make a tough catch.“He was connecting everywhere and people were making plays all over the field,” Odunze said. “When the offense is really
