Statistically, the Bears offense is bad. Would a change in play caller fix that?

It was another quintessential 2020 Bears performance Sunday in Nashville. The defense was as good as it could possibly be without creating turnovers. The offense was about as bad as it could possibly be for three quarters.

Just how bad is the Bears offense? Let's take a peek in Bear Down, Nerd Up, our weekly stat breakdown.

Here are the per game rankings out of 32 teams:

• 19.8 points (28th)

• 317.8 total yards (29th)

• 82.3 rushing yards (32nd)

• 235.4 passing yards (21st)

• 19.8 first downs (27th)

• 32.3% on third-down conversions (31st)

• 50% red zone touchdown conversion (30th)

The Bears have seven games to figure this out. The trade deadline has passed, so this is the personnel they'll have.

Head coach Matt Nagy said again Monday he's not opposed to giving up play-calling duties, but he's not going to announce it.

"I'm looking at all that," he said. "I meant what I said (Sunday). Where we're at as an offense, and struggling the way we are, you have to look at everything, including myself."

Changing the play caller brings no guarantee of success. Game planning for the offense is a collaboration between Nagy, offensive coordinator Bill Lazor, passing game coordinator Dave Ragone, quarterbacks coach John DeFilippo and others.

The collaboration isn't going to change if the play caller changes. The playbook isn't going to change. The manner in which the Bears use it might, but is that really enough to create any meaningful change with the season more than half over?

"The amount of preparation and the amount of time that goes into it, to give your team the best chance of success is very time consuming," said DeFilippo, who called plays for Minnesota in 2018. "It's a hard job, but you trust your preparation. All you can do as a play caller is put all your time and energy into preparing not only the players, but preparing your mind and yourself for the certain situations that may happen."

It's hard to see Nagy giving up play calling. He's an offensive-minded coach. From his perspective, you only get so many shots at being a head coach in the NFL. You might as well do what got you here - do it your way.

Playoff chances: FiveThirtyEight gives the 5-4 Bears a 57% chance to make the playoffs and a 17% chance of winning the NFC North. It projects the Bears to finish 9-7.

ESPN's Football Power Index is less enthusiastic. It gives the Bears a 34.6% chance to make the playoffs. It projects an average of 8.1 wins.

If the season ended today, the Bears would be out of the playoffs.

Speed demon: The Bears fastest ball carrier Sunday was Barkevious Mingo. The outside linebacker rushed for 11 yards on a fake punt in the second quarter. It gained a first down and was the most exciting offensive play of the first half.

According to NFL Next Gen Stats, Mingo reached 20.33 mph on the run. It was the 11th-fastest run of Week 9. Bears outside linebackers coach Ted Monachino said he had a conversation with Mingo after what was Mingo's first career carry.

"He remembered it just like all of us do when something great happens, you remember every little detail of it," Monachino said.

Where's the rush?: ESPN analytics uses a metric it calls "sacks created." A player is credited with a sack created if he is the first player to win the matchup against an offensive lineman, rather than the player who finishes the sack.

ESPN analytics writer Seth Walder tweeted a list of the NFL's leaders in "sacks created." The top three on the list are quite familiar names: the Rams' Aaron Donald (11 sacks created), the Browns' Myles Garrett (9) and the Bears' Khalil Mack (8).

While Mack has only 6.5 sacks this season (tied for eighth in the NFL), he has helped to create an additional sack and a half.

The Bears created three sacks Sunday, but none went to Mack. Mario Edwards Jr., Bilal Nichols and Roquan Smith each had one.

Outside linebacker Robert Quinn saw his biggest share of snaps this season with 75% of snaps (41 total snaps).

"I'm trying to give him more of an opportunity to get into a rhythm," Monachino said.

Further proof that passer rating is misleading: If you hadn't watched Sunday's game and looked only at the stat line, it was Nick Foles' best game of the season. Such a perception doesn't pass the eye test.

Foles was 36-for-52 passing for 334 yards and two TDs.

His 99.4 passer rating was his highest of the season and his highest throughout a full game since he recorded a 102.1 in Week 16 of 2018 with the Philadelphia Eagles (Foles had a 132.8 passer rating in Week 1 of 2019 with Jacksonville but played only 11 snaps before breaking his collarbone - so I'm tossing that out).

A look at ESPN's "total QB rating" shows a different picture. Passer rating, the NFL's official stat, simply looks at the raw numbers in the stat sheet. ESPN's total QB rating takes into account situational difficulty and strength of opponent, among other factors.

Foles' 39.7 total QB rating was only slightly better than his 39.5 against the Rams two weeks earlier. According to total QB rating, Foles' worst game came against the Indianapolis Colts in Week 4 (35.5).
