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 XVIII
The Raiders were the first team to score an offensive, defensive, and special teams touchdown in the same Super Bowl. The Redskins became the second defending champion to lose a Super Bowl (their divisional rivals, the Dallas Cowboys, were the first, losing Super Bowl XIII after winning Super Bowl XII). The Redskins would be joined by the Green Bay Packers in 1998 (won Super Bowl XXXI, lost Super Bowl XXXII), the Seattle Seahawks in 2015 (won Super Bowl XLVIII, lost Super Bowl XLIX), and the New England Patriots in 2018 (won Super Bowl LI, lost Super Bowl LII).
