The Chicago Bears have climbed back into the NFC playoff race, but to keep their momentum, they need to pull off an upset on Sunday against the Chicago Bears. It's going to take a near-perfect game to pull off the upset, but it can happen.

Let's breakdown four reasons the Bears can pull off the upset against the Packers.

4. Khalil Mack has terrorized the Packers before

The first time the Packers and Bears faced off during the 2018 season Khalil Mack was dominant and he can do it again. Mack forced two turnovers during that game including a pick-six.

So far this season, Rodgers has been sacked 31 times and Mack is going to be a problem for the Packers' offensive line. If they try to double and triple-team him, it's going to open up other pass rushers to put pressure on Rodgers.

3. Allen Robinson is heating up

Allen Robinson is heating up and has a touchdown in each of the team's last three games. It's clear he is someone that Trubisky trusts, and when throwing to the end-zone, Robinson is the number one target.

The Packers aren't particularly good at pass coverage and Robinson and the rest of the wide receivers should be in line for a big game. Much like Mack on the defensive side of the ball, if Green Bay tries to key on him that should open up some of the other members of the offense like Anthony Miller to have a big game.

2. Bears rushing defense against Aaron Jones

The Chicago Bears have a huge advantage in this game and it involves their defense going against running back Aaron Jones. These two teams faced off once already this year and Aaron Jones wasn't a factor in that game. Jones rushed 13 times for  39 yards and zero touchdowns.

On the season the Bears are giving up only 96.3 yards per game, which ranks 7th in the league. When the Packers become a one-dimensional offensive attack, they're not as strong and the Bears should have success taking away Jones as a result.

1. The recent resurgence of Mitchell Trubisky

Who would have thought a month or two ago that Mitchell Trubisky would actually be an advantage for the Bears? After a terrible start to the season, he is playing a lot better as of late and there is no reason he can't have a big game in this one. In each of the last couple of games, he has thrown three touchdowns.

Last season, Trubisky's ability to get the job done with his legs was a big part of his game and he is finally starting to use that to his advantage again. In the last game against the Dallas Cowboys, he rushed 10 times for 63 yards and a touchdown.

“It was very evident that he used (his legs) as a weapon,” Bears coach Matt Nagy said via Bears Wire. “We saw some things that we liked in regards to the run scheme.

“And, heck, whenever he’s able to use his legs like that, he becomes another running back. … They’ve got to respect that. They have to understand where he’s at. And when you make good decisions and you’re able to use your own self as a ball carrier, there are advantages across the board.”

Look for Trubisky to use his legs and arm to lead the Bears to victory.
