The Seattle Seahawks were struggling a week ago, coming off their bye having lost five of their last six games. That included a gut-punch overtime defeat at home against the Los Angeles Rams on Nov. 3.

The San Francisco 49ers made their onetime house of horrors look like their home stadium Thursday night. With the once-filled stands at Lumen Field awash in red late in the fourth quarter, the 49ers finished off a 31-13 beatdown of the Seahawks to seize control of the NFC West with six regular-season games remaining.
