Reasoning: [structural reuse of KXNFLAFCCHAMP-27-DEN/KXSB-27-DEN] Winning the Super Bowl (Pro Football Championship) requires winning the AFC Championship game first. So if Denver wins the Super Bowl, they must have won the AFC Championship. The reverse does not hold — winning the AFC Championship does not guarantee winning the Super Bowl.
