American football rules
Super Bowl LI was the first Super Bowl to go into overtime with a 28-all tie between the Atlanta Falcons and New England Patriots, which the Patriots eventually won with James White scoring a touchdown on the Patriots' first drive.
Tony Eason
The Patriots made their first appearance in a Super Bowl in franchise history that year, meeting the Chicago Bears with Jim McMahon and Walter Payton. The Bears' famed 46 defense defeated Eason and the Patriots in Super Bowl XX, and Eason became the first starting quarterback in Super Bowl history not to complete a pass, going 0-for-6. Eason was replaced with Steve Grogan, but the Patriots still lost the game, by a final score of 46–10, which was the largest winning margin of any Super Bowl up to that time.
