Any skeptics left doubting the merit of Caleb Williams' nickname might look to the mercury for confirmation on Sunday night when the Chicago Bears and Los Angeles Rams stage the finale of a four-game NFL Divisional Playoff weekend.

Williams' late-game heroics and growing legend for cool under pressure hit a new level last week. He led Chicago back from a 21-3 deficit with a team-playoff record 361 passing yards to lift the Bears over the rival Green Bay Packers, the first postseason win for the franchise since 2011. It was the seventh game-winning fourth-quarter drive for Williams this season.

'I feel calm in those moments. I feel my conditioning is the best in those moments. I feel that I'm the best in those moments because of what I've prepared to be in those moments,' Williams said. 'For myself, it's just 'next play, next play, next play,' and then when you have to go make a play, it's life or death in those moments.'

As the Rams roll into Chicago (12-6), the No. 2 seed in the NFC playoffs, the challenge is heating back up following a 34-31 win over the Panthers in the wild-card round last Saturday. Frigid temperatures are in the forecast for gametime -- highs in the teens with snow flurries around kickoff time at 6:30 p.m. ET.

A little precipitation and chill might not hurt Rams quarterback Matthew Stafford, who is 4-1 at Chicago in his career when the kickoff temperature is below 40 degrees. He's not alone. L.A.'s lead running back, Kyren Williams, is from St. Louis and played at Notre Dame. Wide receiver Davante Adams, the NFL leader with 14 touchdown catches, spent the first eight seasons of his career with the Packers and knows his way around frosty Soldier Field, too.

Stafford said he's not feeling any pain or lingering issues with his sprained right index finger. He was hurt at Carolina last week but didn't miss a snap and led the Rams to a comeback win with 304 yards and three TDs.

Williams had 3,942 passing yards and 27 touchdowns in 2025. The Rams are quick and relentless along the defensive line and had 47 sacks in the regular season. Los Angeles (13-5) will test Williams' eye discipline and gauge the readiness of left tackles Theo Benedet and Braxton Jones, activated from injured reserve this week. Both have started this season, but the Bears lost Ozzy Trapilo (knee) to a season-ending injury against the Packers.

'Obviously it's a bit of a whirlwind,' Benedet said of coming off the bench last week for the game-winning drive and resuming his role as the starting left tackle.

It's not unthinkable the game could be won by two dudes under stocking hats on the sideline.

Rams coach Sean McVay and Bears coach Ben Johnson are regarded as two of the game's brightest offensive minds. McVay enters his 15th career playoff game against a 15th different team but is very familiar with Johnson, who shares common pupils with McVay in Stafford and Lions quarterback Jared Goff. Before McVay helped pry Stafford from Detroit in a trade, Johnson was on the coaching staff with the Lions for two seasons. Then the Rams sent Goff to the Lions in the QB swap.

'He does a great job. I've studied him really closely since he took over and started it doing it in Detroit,' McVay said. 'I think what shows his flexibility is the ability to have one of the best offenses with a player like Jared, who's really special, and then being able to have some similar foundational principles with Caleb but also accentuate the things that make him really unique with the athleticism, move the spot and take advantage of their skill around it.'

Bears fans will recognize the bloodlines of the Rams' offensive coordinator -- Mike LaFleur -- and Packers coach Matt LaFleur and McVay are longtime friends and coaching allies from their days as assistants with the Washington Commanders organization.

Did McVay phone a friend for tips on taking down the Bears?

'What do you think? We watch the tape, we do our work, and Matt is a very close friend of mine,' he said.

Year 17 has been a brilliant season for Stafford. He led the NFL in passing yards (4,707) and touchdowns (46) in the regular season. Adams and Puka Nacua, the league leader with 129 receptions, loom as massive worries even for a defense that was first in the NFL in interceptions (23) and takeaways (33).

'I've got so much respect for that guy. You talk about the ultimate competitor,' Johnson said. 'He's one of the more talented throwers of the football I've ever been around. He's outstanding. He's a great teammate. ... His toughness. Physical toughness.'

McVay said the Rams are spending extra time drilling all 11 defensive players on playing until they hear a whistle because of Williams' flair for flourishing on unrehearsed extensions of busted plays.

'Some of those second reaction plays where he's getting flushed to his right or getting flushed to his left and guys understand how to be able to work with him,' McVay said, 'those are the ones that are really scary.'

When he lost No. 1 wide receiver Rome Odunze for five weeks due to a foot injury, Williams turned to rookie tight end Colston Loveland to fill that void. Loveland, the No. 10 overall pick in the 2025 draft, had eight receptions for 137 yards last week.

'I know Caleb has an immense amount of trust in him,' Johnson said. 'He's one of the first ones in the building every single day. He is always studying his playbook while he's eating breakfast. He is always the last one off the practice field, doing the jugs machine. Model of consistency, which for a rookie speaks volumes.'

The winner of Sunday's game plays in the NFC title game next week, meeting either the San Francisco 49ers (13-5) or Seattle Seahawks (14-3).

The Rams beat the 49ers in the 2021 NFC Championship, 20-17, and beat the Saints in the 2018 conference championship game.

Chicago last won the NFC Championship Game in 2006 and also won in 1985 prior to winning Super Bowl XX. The Bears lost the 2010 NFC Championship to the Packers.

Rams nose tackle Poona Ford (elbow) and offensive lineman Kevin Dotson (ankle) were limited on Wednesday but plan to play Sunday. Dotson has been out since he was hurt in Week 16 against the Seahawks.

Dotson is an essential cog in the running game.

'He's a beast. When he was playing this year, I thought he was one of the best guards, if not the best guard in the league,' Stafford said. 'So if we can get him back, obviously that would be a huge boost.'

Odunze and wide receiver D.J. Moore (knee) were limited to start the week but Bears safety C.J. Gardner-Johnson (concussion) was a full participant in Wednesday's practice.
