Packers right tackle Jason Spriggs had a grip on Khalil Mack, so the Bears outside linebacker couldn't turn around to face the quarterback he was trying to flatten.
So Mack found a creative way to add to his sacks total this season — now at 12 1/2 after the Bears' 24-17 victory over the Packers to clinch the NFC North title on Sunday at Soldier Field.
As if trying to limbo, Mack bent his back toward Packers quarterback Aaron Rodgers, who was behind him struggling to stay upright with Bears defensive lineman Bilal Nichols also pulling him down.
Then Mack sat on Rodgers' legs to complete the takedown — or "The Mack Back Sack" as it was dubbed by some on social media. The second-quarter play wasn't the most important of the Bears' five sacks against Rodgers on Sunday — those were the three that came in the fourth quarter — but it was the most unconventional.
"By any means necessary," Mack said of the sack he split with Nichols. "The guy kind of grabbed my face mask, so I couldn't even look at the quarterback. I didn't know where he was at. I'll take it if they gave it to me."
Rodgers entered the game with just four turnovers all season, but he had been sacked 39 times, and a Packers offensive line without starting right tackle Bryan Bulaga was vulnerable.
Mack had 2 1/2 sacks, and outside linebacker Leonard Floyd, who entered with two sacks this season, doubled his total with two more. They each had six tackles.
After the game, as the Packers contemplated being eliminated from the playoffs by their rivals, Rodgers rattled off the players who made his day difficult.
"(Mack) is the kind of player, just like Aaron Donald when you play in L.A., you have to figure out where he's at every play," Rodgers said. "You're pairing him with Floyd, who is a legitimate pass rusher, Eddie (Goldman), who has had a great season, Akiem (Hicks), who is very disruptive. It's a tough front."
Floyd's first sack sent a message that the Bears defense wasn't going to crumble late in the game as it did in the season-opening loss to the Packers, even though outside linebacker Aaron Lynch went down with an elbow injury earlier in the second half.
After Tarik Cohen fumbled on a direct snap at the Packers 27-yard line with the game tied 14-14 in the fourth quarter, Floyd took down Rodgers for a loss of 2 yards on the Packers' next play. The Packers went three-and-out on the drive.
"We knew we were going to have to rush as a unit, make sure we stayed in our lanes, not giving him too many opportunities to break the pocket and make big throws," Floyd said. "The first game, we felt like we should have won. This game we wanted to make sure we came out and finished in the second half."
After the Bears took a 21-14 lead, Mack sacked Rodgers on the Packers' next play from scrimmage, and the Packers went three-and-out again. Mack also was rounding the corner to pressure Rodgers when Eddie Jackson became just the second player to intercept him this season on the following drive.
And Floyd finished the harassment with 24 seconds to play, taking down Rodgers for a loss of 18 yards. That prompted the Packers to kick a 45-yard field goal, followed by an unsuccessful onside kick.
"Leonard showed up and showed out," Mack said. "That's a special dude on the other side. We knew it was going to take both of us getting after him. It was good to see."
After the game, while wearing his NFC North champions cap, Mack ran along a Soldier Field wall, reaching up to give high-fives to fans along the way. The outside linebackers' performance was cause for celebration. But afterward in the locker room, Mack wasn't ready to talk about the playoffs or the Bears' accomplishments since he joined the group in September.
"My best-case scenario? It hasn't happened yet," Mack said. "We have the NFC North title so far, but we want to make this push. . We have two more games left we have to win (in the regular season)."
