The Seattle Seahawks’ miserable night at the Coliseum never got much better after running back Rashaad Penny sprained a ligament in his left knee on the opening drive. The Seahawks absorbed a 28-12 loss to Los Angeles Rams that snapped their five-game winning streak and their streak of 43 consecutive games with an offensive touchdown. The defeat didn’t really alter Seattle’s path to the postseason and a chance to play for the NFC West title. But the Seahawks learned they’ve still got plenty of work to do.
