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. That could provide an edge over Bills rookie Tyler Bass — except that Bass has been very reliable all season. Buffalo punter Corey Bojorquez and Kansas City rookie Johnny Townsend were two of the most dependable in the AFC.
