It has been a difficult journey for Buffalo Bills defensive end Efe Obada.

The Kansas City Chiefs won their first NFL title since 1970 when they beat San Francisco in last year's Super Bowl. What we get Sunday is a matchup of dynamic offenses and overlooked defenses, the top two teams in the conference. Kansas City (15-2) has the confidence of a reigning champion and a charisma few NFL teams can match.

Buffalo punter Corey Bojorquez and Kansas City rookie Johnny Townsend were two of the most dependable in the AFC.
