Kansas City #Chiefs defensive tackle Chris Jones gives a ringing endorsement for defensive coordinator Steve Spagnuolo | @EdEastonJr

Kansas City’s defensive coordinator showed his importance in Sunday’s AFC championship. It’s long overdue that he gets another shot at being a head coach.

The Kansas City Chiefs' defense pulled off a strategic masterstroke to eliminate the Buffalo Bills from the playoffs.

Another week, another trip to the Super Bowl for the Kansas City Chiefs, and another coaching masterclass from Steve Spagnuolo. A key piece to Kansas City advancing to its fifth Super Bowl in the last six seasons and now set to attempt the NFL's first-ever three-peat was the defensive effort led by Spagnuolo,

The game — and the Chiefs’ historic charge toward an unprecedented Super Bowl three-peat — was slipping away Sunday night in Kansas City.

The situation came on the other side of the two-minute warning on Sunday night. With Kansas City clinging to a 32-29 lead, Allen and the Bills faced a do-or-die 4th-and-5 situation on their own 47-yard line. With Buffalo holding all three of their timeouts, Sean McDermott left his offense on the field to try and convert fourth down.

Here are 10 of the top reasons the Chiefs are Super Bowl-bound yet again: 1. They are inevitable. Let's just start here. The Chiefs are a dynasty.

The Buffalo Bills are still in championship purgatory, and one play in particular doomed them, because they ignored one primary schematic trait from Steve Spagnuolo

Chiefs defensive coordinator Steve Spagnuolo pulled out one of his best calls when his team needed it against the Bills.

Kansas City Chiefs DC Steve Spagnuolo dialed up an unexpected corner blitz in a pivotal moment against the Buffalo Bills.

Yes, cornerback Trent McDuffie — historically an excellent pass-rusher from the outside, and one who helped save the Chiefs in last year’s Super Bowl with a well-timed rush — got the green light to attack Bills quarterback Josh Allen. Or, perhaps, he made that decision on his own.

The Chiefs will face the Eagles in Super Bowl LIX after defeating the Bills in the AFC Championship. Chiefs' Chris Jones credits defensive coordinator Steve Spagnuolo's coaching for their success, emphasizing his importance to the team.
