Bill Belichick and the New England Patriots are at home in Houston, where they won Super Bowl XXXVIII, and accustomed to the NFL's biggest stage.
The Atlanta Falcons are in their second Super Bowl and strive to secure the Lombardi Trophy for the first time in franchise history on Sunday in Super Bowl LI.
The Falcons, in head coach Dan Quinn's second year, rode the NFL's highest-scoring offense (33.8 points per game) to the top of the NFC. The trophy on the line Sunday is the hardware that matters, but Atlanta's achievements already include offensive coordinator Kyle Shanahan being named assistant coach of the year and Matt Ryan as offensive player of the year. The MVP award is handed out Saturday night, and Ryan is expected to win that award.
Quinn's defense was 27th in the NFL in points allowed and starts four rookies, which could be viewed as blood in the water for Brady, who is one win from setting the modern-day record with five Super Bowl wins.
In 12 games this season, Brady was sacked just 15 times and had a TD-to-INT ratio of 28-12. Against Atlanta, a defense built on speed, the Patriots could install an extra offensive lineman or tight end and play power football to force the Falcons to adjust.
