A record 123.4 million people tuned in to watch the Kansas City Chiefs beat the San Francisco 49ers in Sunday's Super Bowl -- with the added attraction of an Usher-headlined halftime show and the attention-stealing presence of Taylor Swift. Chief's quarterback Patrick Mahomes found Mecole Hardman in the end zone deep into overtime to seal a dramatic 25-22 win in what was also the longest Super Bowl game in history. The victory makes Kansas City the first team to win back-to-back Lombardi Trophies since the New England Patriots in 2003-2004, cementing the franchise's right to be regarded as the NFL's newest dynasty.
