ATLANTA — Two Sundays ago at Arrowhead Stadium, one quarterback thrived on the field and another in the broadcast booth during a fourth quarter full of fireworks.

Both delivered a winning effort.

After New England beat the top-seeded Chiefs 37-31 in overtime of the AFC championship, the only question was which of the two had the better game: Tony Romo, who correctly and incredibly predicted several Patriots plays with tens of millions viewers watching on CBS. Or Brady, who led two touchdown drives to win despite completing less than 50 percent of his passes on those possessions.

Whatever your preference, Romo, a former Pro Bowl quarterback himself with the Cowboys, can explain exactly how Brady thrived in crunch time and how he’s continues to do so late in his career.

“It’s a combination,” Romo told reporters Tuesday. "There’s no one specific thing. It’s his ability to get to the right play, his ability to throw the football at a very high level, his calmness, his poise, his understanding of just situational and time management. And then just having all the years of experience under his belt.

"Now it’s just — If he has 10 chances, he’s going to do it eight or nine of 'em. And then he’ll miss one just because the ball bounces weird and funny sometimes. But he’s just very hard to beat. ... To me, when I got older, you basically see the whole game. And now it’s the fourth quarter and you kind of know what they can and can’t do. And so you’ve kind of figured out a little bit of their plan, so you know how to beat it schematically. And so you kind of get into the plays that kind of give them trouble.

“And it’s really hard to beat Tom because he sees the whole game. And now he has that advantage. And then the pass rush is usually just a little bit not quite as fast as they were early in the game. So you tie all that in and it’s like, ‘Good luck stopping him.’"

There’s a chance New England will need Brady to captain another comeback on Sunday against the Rams in Super Bowl LIII. The Patriots are only 2.5-point favorites, and Los Angeles boasts an explosive offense, which helped the team go 18-0 in the games it’s held a halftime lead since 2017. Of course, if called upon to command a two-minute drill, the Pats' confidence in Brady will unquestionably be as high as Romo’s.

After all, two years ago Brady led the largest comeback in Super Bowl history, overcoming a 28-3 deficit late in the third quarter of Super Bowl LI to beat the Falcons. In his first Super Bowl appearance, Brady directed a game-winning drive to conquer the heavily favored Rams in Super Bowl XXXVI as time expired. Over the years, he’s amassed 44 fourth-quarter comebacks and 56 game-winning drives; the last of which sent New England back to the Super Bowl just 10 days ago.
