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.
History of the New England Patriots
After routing the Denver Broncos 45–10 in the Divisional Game, the Patriots won the AFC Championship Game, defeating the Baltimore Ravens 23–20, after Ravens receiver Lee Evans dropped a potential go-ahead touchdown and kicker Billy Cundiff missed a game-tying 31-yard field goal attempt in the closing seconds. Seeking revenge from their defeat in the regular season, the Patriots came up short against the NFC champion New York Giants 21–17 in Super Bowl XLVI, a rematch of the team's previous Super Bowl loss.
