Its because the Chiefs offense has been that bad. They are at Tyrod Taylor production the last 2 years.
The offense was worse that the defense in this past Super Bowl. 23 yards at half time, punted the ball 5 times and had 2 INT's. You can't keep giving a team like the Eagles the ball back.
In 2023, the Chiefs playoff opponents averaged 15 ppg. They allowed 10 to the #1 seed Ravens at Baltimore.
Without a top level defense, the Chiefs aren't getting anywhere near the Super Bowl.
