Overreactions from 49ers win over Rams: Kyren Williams costs L.A. NFC West? Mac Jones remains 49ers' starter?

Here is a 186-word summary of the news article: The San Francisco 49ers' win over the Los Angeles Rams has sparked several overreactions from fans and analysts. One is that Rams rookie running back Kyren Williams' costly fumble could have major implications for the NFC West division race. However, it's too early to say if that single play will determine the division winner. Another overreaction is that 49ers quarterback Mac Jones will remain the starter over Trey Lance, despite Lance's injury. But the 49ers have consistently supported Lance as their QB1, and it's unlikely this one game will change that. The article also addresses the notion that the 49ers have "the Rams' number" after winning three straight against them. While the 49ers have had success, the Rams are still the defending Super Bowl champions and a formidable opponent. Overall, the article cautions against drawing definitive conclusions from a single regular-season game, emphasizing that it's important to maintain perspective and avoid knee-jerk reactions, even after a significant win.
