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.
Super Bowl XXXVI
Coincidentally, this was the third straight time that the New England Patriots' Super Bowl appearance was hosted in New Orleans. The Patriots did not appear in a Super Bowl hosted by another city until the team played in Super Bowl XXXVIII two years later in Houston, Texas. They joined the Dallas Cowboys as the only teams to play three different Super Bowls in one stadium. The Cowboys played three at the old Miami Orange Bowl in the 1970s.
