SANTA CLARA – The 49ers have not played many big games over the past five seasons. But this is the year that changes.
Coach Kyle Shanahan’s team is the only unbeaten squad remaining in the NFL. They can take a major step toward the franchise's first division title since 2012 with a victory Monday night over the Seattle Seahawks at Levi’s Stadium.
The 49ers can take a three-game lead in the loss column over Seattle and the Los Angeles Rams. But a loss would mean the Seahawks would move just one game behind the 49ers and remain unbeaten in the NFC West with a rematch against the 49ers coming Week 17 in Seattle.
