First, it was the Kansas City Chiefs' defense that looked like their Achilles heel early this season. Then the offense struggled to a degree few thought possible with Patrick Mahomes at quarterback.
But in Sunday's 48-9 win over the Las Vegas Raiders, the Chiefs turned in the type of complete-game performance that should serve as a reminder: They absolutely remain Super Bowl contenders.
Perhaps they should be considered as one of the favorites. The 48 points were tied for the second-most scored by an NFL team this season. And the Chiefs now have allowed nine or fewer points in four of the past five games, including three straight.
