It was around this time last year that the San Francisco 49ers found themselves in a difficult spot heading into their bye week. Brock Purdy is NOT the Answer for the 49ers, says Shannon Sharpe Brock Purdy is NOT the Answer for the 49ers, says Shannon Sharpe Brock Purdy is NOT the Answer for the 49ers, says Shannon Sharpe The Kansas City Chiefs had just beaten them soundly at Levi's Stadium to drop to 3-4 on the season. But the biggest solution to that team's problems was already in the building. The Niners acquired running back Christian McCaffrey in a blockbuster trade a couple days earlier with the idea that he could spark a second-half run. He did, and the Niners ripped off 10 straight wins to close the season on the way to an NFC Championship Game appearance. Little more than a year later, the Niners head into their bye and Tuesday's NFL trade deadline with a much better record but just as much urgency to right the ship after Sunday's 31-17 loss to the Cincinnati Bengals. After a 5-0 start, the loss to the Bengals was San Francisco's third in a row, dropping them to 5-3 and out of first place in the NFC West division. "No, none of this changes anything with the trade deadline," Shanahan said. "How we played today or how we played these last three weeks. ... I do believe we have the answers in our building. I believe we have good players. I believe we have good coaches. It's up to me to get them to do better. Sunday's loss was the Niners' first three-game losing streak since the 2021 season and comes on the heels of a stretch in which they had won 15 straight regular-season games (tied for a franchise record) and beat their first five opponents this season by an average of 19.8 points per game. Even during their early season domination, Shanahan had alluded multiple times to the mistakes his team was making but able to get away with because it had jumped out to big leads. Penalties and red zone woes had been problematic but the Niners offset many of those by making big plays on offense (21 plays of 20-plus yards was sixth most in the NFL) and giving up few on defense (10 20-plus yard plays allowed were fewest in the NFL). They'd also been dominant in the turnover battle, going plus-7 with a league-low two giveaways. The past three weeks have offered a dramatic shift in the opposite direction for most of those categories. The Niners have been outscored by an average of 7 points per game, outgained by an average of 62 yards per game and have given up 15 plays of 20-plus yards (the second most in the NFL in that span). What's more, the Niners have turned the ball over seven times (tied for fourth most) and are minus-3 in turnover margin (also tied for fourth worst) in that span. After not throwing an interception the first five weeks, Niners quarterback Brock Purdy has thrown five in the past three games, including four in opposing territory, one of which came inside Cincinnati's 10 on Sunday. The compounding mistakes have also limited the Niners' ability to run the ball often or effectively. That was the case the first five weeks but hasn't been of late. As the schedule and quarterbacks they face have gotten tougher, the Niners have given up almost 70 passing yards more per game through the air and opposing quarterbacks have a QBR nearly 16 points higher over the past three weeks. Those issues combined with a pass rush that has struggled to get home and a controversial blitz call before halftime of last week's loss to the Minnesota Vikings have put Wilks under the microscope. But Shanahan said Sunday that there's plenty of blame to go around. "This isn't on any one coach or any one side of the ball," Shanahan said. "We haven't scored over 20 points here in three weeks, too. So, I think our defense needs to do better. I think our offense needs to do better. I think our team needs to do better. When I say our team, I mean every single player in there and I think every single coach." Now, the 49ers head into a long layoff th
