Bears @ Falcons

Worst offense for two weeks, best for three. The Bears get the second version.

Through two weeks the Falcons had the worst offense in football: minus 0.403 expected points per play, 32nd of 32, and 16 points in two losses with Cooper Rush starting. Michael Penix Jr. has started the three games since, and over Weeks 3 to 5 Atlanta leads the league at plus 0.234 per play and in points, 103, one more than Detroit in that stretch. Penix is averaging 9.34 yards per attempt, second among passers with 70 or more attempts, and Bijan Robinson leads the league with 580 rushing yards. Chicago arrives off a 31 to 7 loss at Green Bay with a defense that has allowed the second lowest third down rate in the league. The question for Sunday is whether that defense can get this Atlanta offense off the field.

Week 5 cut against both teams' 2025 form in different ways. Atlanta's offense posted minus 0.022 per play against Baltimore, 17th of the 30 teams that played, almost exactly its 2025 average of minus 0.021, 24th. Chicago's offense posted minus 0.340 at Green Bay, 26th of 30, after plus 0.079 and eighth across 2025, and its defense allowed plus 0.259, 27th, against plus 0.018 and 19th in 2025. Each is one game, set beside a full season.

Why it matters. Atlanta went from last in the league over two weeks to first over the next three, and the change lines up exactly with the switch at quarterback. The Week 5 loss to Baltimore is the caution, an ordinary night close to Atlanta's 2025 level. Chicago's defense brings the one number that directly attacks a hot offense, third down, while the Bears' own offense is coming off its worst game of the season. Every collision below is a version of the same question: does the Penix offense keep the ball?

Atlanta converts on third down again. Chicago allows the second fewest.

The Penix change shows up most clearly on third down. Atlanta converted 6 of 25 in Weeks 1 and 2, 24.0 percent, and 19 of 35 since, 54.3 percent, second in the league over Weeks 3 to 5, after converting 34.1 percent in 2025, 30th. Chicago's defense has allowed 13 conversions on 50 third downs, 26.0 percent, second behind Minnesota, and it held the Jets to 0 of 7 in Week 4; in 2025 it allowed 40.8 percent, 19th. The Bears have also faced the fewest offensive plays in the league, 250, while their own offense has run the most, 360. If Atlanta converts two of its first three third downs, the Bears' defense spends Sunday on the field; if Chicago forces two early punts, the game moves toward the Bears' play count.

Why it matters. This is strength against strength on the down that decides possessions. Atlanta's third down offense in the Penix starts is second in the league, a sharp break from its 30th place finish in 2025, and Chicago's defense has the second best rate allowed, a sharp break from 19th in 2025. Both are three to five game samples set against full seasons. The Bears' play count is the hidden part: their offense has run 110 more plays than their defense has faced, and a defense that rarely sees third down looks better for it. A long Falcons drive tests whether that number holds up.

The two most run heavy offenses meet, and Bijan Robinson leads the league.

No team runs more often than Atlanta, 52.4 percent of its plays, and no team has run more times than Chicago, 178. Bijan Robinson leads the league with 580 rushing yards, and the split by quarterback matches the rest of the offense: 4.19 yards per carry and no touchdowns in the two Rush starts, 6.54 and four touchdowns in the three Penix starts. Chicago's run defense is 23rd of 32 in expected points allowed per carry at 4.50 yards a carry, close to its 19th place in 2025. The Bears' own run game is eighth in expected points per carry, after fourth in 2025, against an Atlanta run defense that is 14th. Both teams ran far less in Week 5 while trailing, Atlanta 40.6 percent and Chicago 35.3 percent. If both teams are still running on first down in the second quarter, the game is close and on the terms both offenses want; the first team that has to stop running is the team that is behind.

Why it matters. Both offenses are built to run, and in 2025 neither was in the top eight in run rate, so this is a 2026 identity for both. Robinson is the clearest single reason Atlanta's offense swung, and his per carry average is more than two yards higher in the Penix starts. Chicago's run defense is ordinary, which makes Robinson the edge to watch, and Atlanta's run defense is ordinary too, which keeps the Bears' ground game alive. Run rate is also a score signal, as both teams' Week 5 numbers show.

Two 2025 ball hawks have four interceptions between them.

Chicago's defense led the league with 23 interceptions in 2025 and has three through five games. Atlanta's defense made 16 in 2025, sixth, and has one, tied for second fewest, on 222 dropbacks. The Bears' passers have given the ball away more than last year's offense did: five interceptions across three quarterbacks, three of them at Green Bay in Week 5, after seven all of 2025, fewest in the league. Atlanta has thrown seven, tied for most, but six of them came from the quarterbacks who are not Penix, and he has one on 82 dropbacks. If Chicago's quarterback reaches halftime without an interception, the Falcons have to win the game with their offense; if the Bears take one from Penix early, they have done what only Green Bay has managed against him this season.

Why it matters. Takeaways were the defining trait of both defenses in 2025, and neither has found them in 2026, so the ball security of each quarterback room matters more than the defenses' reputations. Chicago's three interceptions at Green Bay were one game, from Tyson Bagent and Case Keenum, set against a 2025 offense that threw the fewest in the league. Penix has protected the ball through the same three games in which Atlanta's offense led the league, so the hot streak in the storyline has not been built on risk. One takeaway either way is the swing in a game where both teams want to run.
