The Green Bay Packers raced out to a 14-0 lead but then had to overcome a nightmare second quarter en route to a 31-24 win over the Kansas City Chiefs on Sunday night at Arrowhead Stadium.

The Packers’ fourth-straight win improved Matt LaFleur’s team to 7-1 after eight games in 2019.

Here are the studs and duds from Sunday night’s win:

Studs

RB Aaron Jones: If the rest of the NFL didn’t know Jones was a star, they know it now. His 226 total yards set a new career-high. It was also the third-most total yards in franchise history and the third-most by an NFL player in a game this season. The Chiefs couldn’t contain his elite burst, whether it was in the open field or between the tackles. He showed exactly why Matt LaFleur and Aaron Rodgers trust him in the passing game, executing both an angle route and a sluggo route for big plays. The 67-yard touchdown turned Jones into a punt returner, and he weaved his way around blocks and into the open field. He plays much faster than his 40-yard dash time (4.55) suggests. He scored twice – the first capping off the opening drive, the second providing the go-ahead score in the fourth quarter – but also had two touchdowns taken away, one by penalty and another by review. On the final drive, Jones carried five times for 26 yards and was the primary target on the dagger third-down conversion. There have been a lot of great running back performances in Green Bay Packers history. Jones’ night in Kansas City ranks right up there among the best ever.

OL Elgton Jenkins: Even during the live television broadcast, it was easy to see Jenkins mauling people at the line of scrimmage. His man tallied one of the five sacks on Aaron Rodgers but it was hardly the rookie’s fault – he blocked his guy for over three seconds but Rodgers held the ball and took a bad sack. On the final drive, Jenkins was moving people in the run game. He has such a good feel for coming off the combo block at the point of attack and getting to the second level to erase a linebacker. The rookie was solid right away but he’s getting better and better each week.

RB Jamaal Williams: He’s a utility knife for Matt LaFleur. He was a lead blocker on Aaron Jones’ opening touchdown. He barreled into the end zone from a yard out to give the Packers a 14-0 lead. He busted off a 14-yard run on the Packers’ first scoring drive of the second half. He extended a drive with a quick route and catch on third down. And he kept the play alive in a scramble situation and made an incredible catch of Aaron Rodgers’ impossible throw into the corner of the end zone. He blocks, he catches, he runs with fire. And LaFleur knows exactly how and when to use him. Williams already has five total touchdowns in 2019.

DL Tyler Lancaster: Big No. 95 was the Packers’ best run defender. He also created the game’s only takeaway when he stuck out an arm and stripped the ball from LeSean McCoy as he went waltzing by in the second half. The ball even bounced back to him for the recovery. The takeaway stole a possession for the Packers, and they converted the turnover into seven points.

OLB Za’Darius Smith: He produced the Packers’ only two sacks of Matt Moore. Both times, he beat a backup. On the first, he blew past left tackle Cameron Erving and lassoed down Moore in the pocket. Later, he beat Martinas Rankins one-on-one on the inside and got to Moore on third down, ending the Chiefs’ first drive of the second half. The Chiefs were down two starters and Smith made it hurt.

C Corey Linsley: He overcame a mid-week back issue and was solid in the middle of the Packers offensive line. It was arguably his best game of the season as a run blocker. Several times, he was the anchor of combo blocks with Elgton Jenkins and Billy Turner that opened up running lanes. And he looked good on the move. His highlight play came in the fourth quarter when he marched out in front of Aaron Jones and delivered a key block on the 67-yard touchdown.

QB Aaron Rodgers: The Packers quarterback had an uneven performance but two otherworldly throws land him safely in the “studs” section. Sure, he threw two interceptable passes, including one into the end zone, took several bad sacks and got flustered early by the blitz, but he created 14 points out of thin air with unreal throws to Jake Kumerow on the first drive and Jamaal Williams in the fourth quarter. Both times, Rodgers was flushed to his right and under heavy pressure while throwing. Both times, he put the ball exactly where it needed to be. Both throws converted third downs. The Packers punt on the first drive without the completion to Kumerow, and they likely settle for a field goal without his rainbow to Williams in the corner of the end zone. Those two improbable completions were essentially worth 11 points in a game won by seven.

WR Allen Lazard: Lazard has to be giving GM Brian Gutekunst some pause about trading for a receiver. He caught all five of his targets and was inches away from scoring his second touchdown of the season (ruled out at the 1-yard line), and he proved to be a plus as a blocker on the perimeter. On Aaron Jones’ first touchdown, Lazard blocked his man for close to three seconds. Three different times, he did a nice job of catching a quick pass and following his blockers for a positive gain. He also got open on a scramble drill for 14 yards. Lazard now has 12 catches on 14 targets in 2019.

Duds

LB Blake Martinez: Credit Martinez for playing through a wrist and hand injury that required a club for protection. Playing one-handed is tough as an inside linebacker. Martinez was fine against the run, but the Chiefs relentlessly attacked the middle of the field because they knew they could run receivers behind his zone coverage and create chunk plays. All that speed on the field made Martinez look really out of place at times. Travis Kelce’s long touchdown appeared to be the result of Martinez getting distracted by all the backfield commotion. He also missed at least two tackles in the open field.

CB Kevin King: There was a concerted effort from Mike Pettine and the secondary to play off and keep everything in front to prevent big plays. It made sense in theory but it was tough to execute at times. Several times, King gave up too much of a cushion and got beat for first downs on intermediate routes. Tyreek Hill had him spinning like a top on one 18-yard completion to the boundary. Later, King gave up a 12-yard cushion and Matt Moore took an uncontested completion to Hill for 10 more yards. As has been the case for much of the season, tackling was an issue for King. He can be physical, but too often he’s diving at legs and bouncing right off. On a late third down, King had a chance to stop Travis Kelce short of the sticks, but the big tight end was unhindered by King’s low tackle attempt.

P JK Scott: The Packers’ second-year punter delivered his worst performance of 2019. He hit two punts under 40 yards and had his first punt returned 18 yards to the Packers’ 30-yard line. His net average was 29.3 yards. Clearly, the Packers wanted to focus heavily on directional punting against Mecole Hardman.

PR Darrius Shepherd: He was removed from kick return duty, and his time as the punt returner may be nearing its end. His late mistake on the Chiefs’ final punt could have been a huge turning point. Shepherd has to catch that ball before it gets to the ground. Instead, it rolled to the 2-yard line. He called fair catch on two other punts and made both catches, but he still looks uncomfortable back there. Even a hint of indecisiveness can make or break a returner.
