The undefeated San Francisco 49ers found another way to impress us all on Sunday. Kyle Shanahan and his team dominated Carolina in all three phases of the game, holding the Panthers to just 13 points while scoring seven touchdowns and dropping 51, the most of the Shanahan era. Now the 49ers face another challenge - a short week. They face off against the Arizona Cardinals on Thursday, and while San Francisco is clearly the better team, the 49ers have found a way to lose to their division foes the last eight times they’ve met.
