It all comes down to today as Patrick Mahomes and the Kansas City Chiefs clash with Tom Brady and the Tampa Bay Buccaneers in Super Bowl LV at Raymond James Stadium in Tampa, Fla. While it may be the first time in the big game's history that it has been played on one team's home turf, what isn't new is Brady's participation - he's played in six Super Bowls with the Patriots. And Mahomes is also no newcomer. A year ago, he led the Chiefs over the San Francisco 49ers for KC's first league title in 50 years. Jim Nantz and Tony Romo call today's game for CBS.
