49ers

 You will be witnessing the passing of the torch in terms of defense tonight.
 Baltimore has held that honor for a decade. And while an aging core is still among the best, the 49ers have put together a defense that could dominate for the next decade.
 This defense is fast, physical and flies to the ball. And it has not allowed a rushing touchdown this year.
 A 49ers win clinches no worse than a share of the Western Division title.
