It’s Brock Purdy’s world on Sunday Night Football.The San Francisco 49ers’ franchise quarterback has been on fire lately, playing the best football of his career.Purdy has helped lift San Francisco towards the upper echelon of the NFCGettyCaleb Williams has enjoyed a brilliant second season in the NFLGettyLast week, he threw five touchdown passes against the Indianapolis Colts, and this week on SNF, he picked up right where he left off.He has four touchdowns and counting against the Chicago Bears and is hitting the Dougie all over them. The former last pick of the 2023 draft even made unusual history.Under the lights at Levi’s Stadium, Purdy became the first quarterback ever to record a pick-six, a rushing touchdown, and a passing touchdown all before the first quarter ended.Even his history-making feats carry a certain cool, despite the negative play. And the internet has taken notice.“Purdy is in the zone. He’s toying with us,” Barstool Big Cat, and noted Bears fan, fan posted on X.“Purdy is ballin tonight,” another fan commented.“Mr. Irrelevant—the last pick in his draft class—Brock Purdy carries a bizarrely compelling aura,” more continued to chime in.“Purdy. Nuclear,” one more fan simply stated.Both teams entered the matchup having booked their tickets in the NFC playoffs, but the Bears—who clinched the NFC North after the Green Bay Packers‘ loss to the Baltimore Ravens—and the 49ers are each hunting down the possibility of being the No. 1 overall seed in the conference.After the Seattle Seahawks won 27-10 against the Carolina Panthers, these hopes have been boosted with each team looking to climb to a 12-4 record on the season with one game left to play.Purdy has San Francisco firing on all cylindersGettyThe Bears have clinched the No. 1 seed only three times previously: in 1985 (won the Super Bowl), 1988, and 2006. With the 49ers, who despite their injury-laden season have posted an identical 11-4 record and could also close the gap to Seattle at the top of the NFC West, the two are currently engaged in a three-way battle with the Los Angeles Rams for the division title. But there were also some personal milestones to edge closer to. Caleb Williams treading toward Bears historyEntering the contest, Caleb Williams needed 600 yards from his final two games to become the first Bears quarterback to eclipse the 4,000-yard passing mark. While the former No. 1 overall pick had four 300-plus-yard games as a rookie in 2024, the highest mark he has reached this season is 298 yards. He would therefore need to set a season high across both games to achieve this feat. However, he needs just 439 passing yards to pass the franchise record (3,838 yards) of Erik Kramer, set 30 years ago. Ahead of the game, 49ers head coach Kyle Shanahan spoke very highly of Williams and said, “Caleb is one of the best throwers, most athletic quarterbacks I’ve ever seen in terms of his height, weight, and speed.Bears QB has turned the franchise aroundGetty49ers HC Shanahan praised what he has seen from Williams this seasonGetty Images - Getty“He makes some big-time throws, is extremely scary on the perimeter, can hold onto the ball for a while—not in a bad way but by creating stuff which makes coverages have to hold up forever.“When you have a talented guy like that, who’s got the speed and the size, usually they get a run game, get some bootlegs, and play-actions off of it. You limit how many times you’ve got to drop back, and it makes sense why he’s playing at such a high level.”The inspiring effort from San FranciscoMcCaffrey has played at an All-Pro level this seasonGettyFor San Francisco, this season has been nothing short of a war of attrition.A war they’ve somehow been winning despite key injuries. Losing defensive stalwarts Nick Bosa and Fred Warner hasn’t fazed them, and missing their starting quarterback for six games in the middle of the season didn’t either.Instead, Shanahan kept his team focused, fueled by a relentless ‘next man up’ mentality.Sure, it helps to have Christian McCaffrey doing what he does best, both on the ground and through the air, serving as the team’s undisputed catalyst.And yes, the defense isn’t great, but it’s still been a collective effort from everyone to not only stay afloat but remain in the race for the top seed in the NFC until the very end.Teach ’em how to Dougie, Brock.Stay up to date with the latest from the NFL across all platforms – follow our dedicated talkSPORT USA Facebook page and subscribe to our talkSPORT USA YouTube channel for all the news, exclusives, interviews and more.
