KANSAS CITY, Mo. >> Patrick Mahomes felt as though he needed to apologize after he helped the Kansas City Chiefs beat the Buffalo Bills in the AFC championship game, punching their ticket to the Super Bowl for the third consecutive season.

Not for the outcome, but for quite possibly the worst spike in NFL history.

In a back-and-forth tussle between two of the NFL’s top teams, the Chiefs were driving early in the fourth quarter last weekend for the go-ahead score. Mahomes took off to the right and powered into the end zone and, with his adrenaline amped to the max, scrambled to his feet and attempted to spike the ball — only for it to squib out of his hand and into the sideline.

“That,” Mahomes said, “is why I don’t try to spike the ball.”

It was a natural outburst of unbridled joy, though, from a quarterback whose fiery will to win has become almost legendary. But on the entire drive leading up to the score, Mahomes had been the complete opposite: calm, poised and under control.

In leading the Chiefs into a matchup with the Philadelphia Eagles in New Orleans next weekend, Mahomes was what those in the Kansas City locker room — players and coaches alike — have come to appreciate as “Laid-Back Pat.”

“The pressure part of it, when things can dilate you a little bit — when things are tight — don’t do that to him,” Chiefs coach Andy Reid explained. “He kind of flourishes in those moments when they’re the toughest. He’s just wired that way.”

The best in sports usually are. And make no mistake, Mahomes is among the best.

He already has three Super Bowl rings and is chasing a fourth, along with an unprecedented third in a row. He’s a two-time league MVP who is shattering records with every season that goes by, and the face of a franchise that has reached the level of bonafide dynasty.

“He’s the best player I ever played with,” Chiefs wide receiver DeAndre Hopkins admitted. “I played with J.J. Watt, and J.J. Watt is definitely a Hall of Famer. But Pat is definitely the best player I ever played with.”

And he’s at his best when the pressure is at its most.

Need proof? How about the fact that the Chiefs have won an NFL-record 17 consecutive games decided by one possession. Or that Mahomes has a winning record — 27 wins, 26 losses — in games in which his team trailed in the fourth quarter; the next-best quarterback with at least 25 starts in league history has a winning percentage of just 38.6.

Then consider the postseason, when the pressure is pushed to another level.

When the Chiefs have been within one possession in the fourth quarter or overtime, Mahomes has led them to points on 13 of 14 drives. He’s a combined 40 of 56 for 552 yards with five passing touchdowns, no interceptions and a run TD on them.

In nine playoff games in which Kansas City trailed in the fourth quarter, Mahomes merely produced six come-from-behind wins. In two of the three losses, he at least managed to get the Chiefs to overtime.

“Whatever he’s got to do to get us to the next level, to win the game,” Chiefs tight end Travis Kelce said, “Pat’s going to do it.”
