But then things fell apart for Tomlin's defense, and thus the Steelers, in the second half.
The Packers scored 25 of the first 28 points after halftime. Quarterback Jordan Love completed 20 consecutive passes, and tight end Tucker Kraft ran for more yards after the catch for a a tight end in eight years.
The result was a runaway victory for Green Bay, who knocked off the Steelers at Acrisure Stadium 35-25.
Late in the fourth quarter, the term "Tomlin" was trending on X, and not because Steelers Nation was pleased with the team's head coach.
"Out-adjusted in the second half. Lack of discipline. Glaring miscues. The inability to get stops," The Pittsburgh Post-Gazette's Jason Mackey posted. "With the area of the team you boasted you improved.
"All comes back to Mike Tomlin."
"Pretty sure there's no one else left to blame but Mike Tomlin," wrote NFL analyst Dave Dameshek.
"Well at least the Steelers are skipping that annual tradition where they're 6-2 & Mike Tomlin is getting coach of the year shouts before collapsing in epic fashion," wrote The Score's Daniel Valente.
"Justin Fields -- 32 points. Sam Darnold -- 31 points. Joe Flacco -- 33 points. Jordan Love -- 35 points," wrote a Steelers fan on X.
