Two Bears Rookies Quietly Stole The Show Before Vikings Matchup

The Chicago Bears produced enough offense in Week 1 to keep everyone busy talking about Caleb Williams, D’Andre Swift and Ben Johnson.

Chicago scored 59 points in its season-opening victory over the Carolina Panthers. The Bears rushed for 291 yards, Swift scored three touchdowns and Chicago gave its fans an early look at how explosive Johnson’s offense might become.

One of the more intriguing developments, however, happened on the other side of the ball. Rookie defensive backs Dillon Thieneman and Malik Muhammad II both made strong impressions in their NFL debuts.

Johnson was particularly impressed with Thieneman, saying the rookie was “all over the field.” His performance was good enough to earn Chicago’s first game ball of the season.

Muhammad also received praise from Johnson for his competitiveness and coverage ability. That’s an encouraging development with Justin Jefferson coming to Soldier Field on Sunday.

Dennis Allen on Dillon Thieneman’s Performance Last Week:

“I think Dillon played well last week, and he’s got to make sure that he’s staying in his playbook. His preparation has to be elite this week because we’ve got another opponent coming up that’s a really good team.”

Bears Young Secondary Gets Bigger Test

Thieneman wasn’t particularly interested in turning his strong debut into a personal celebration.

The rookie told the Bears’ official website that he prefers allowing his play to speak for him.

Muhammad expressed a similar attitude after his debut.

Those are nice sentiments in September. The more important question is whether Chicago’s young defensive backs can continue producing when the competition gets tougher.

That opportunity arrives immediately.

Minnesota will be without starting quarterback Kyler Murray, meaning veteran Carson Wentz will make his 100th career start. Wentz isn’t simply being asked to manage the game after replacing Murray last week. He threw three touchdown passes during Minnesota’s 39-22 comeback win over Green Bay.

Then there is Jefferson.

Game Changer In Week Two

Few receivers in football can stress a secondary quite like Minnesota’s superstar. Chicago’s young defensive backs will need to communicate, avoid explosive plays and make Wentz consistently work underneath.

The Bears will have plenty of attention on their offense after what happened against Carolina.

That’s understandable.

But Thieneman and Muhammad provided Chicago with something potentially more significant than one impressive afternoon.

They offered an early indication that the Bears might have found two young defensive backs capable of contributing immediately.
