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
When the NFL and AFL merged in 1970, the Patriots were placed in the AFC East division, where they still play today. The following year, the Patriots moved to a new stadium in Foxborough, Massachusetts, a suburb of Boston, which would serve as their home for 30 years; the team also changed their name to the New England Patriots to reflect the location change, as well as its following throughout the region as its only NFL team (though both New York City teams have substantial followings in parts of Connecticut as well). During the 1970s, the Patriots had some success, earning a berth to the playoffs in 1976—as a wild card-berth—and in 1978—as AFC East champions. They would lose both games. In 1985, they returned to the playoffs, and made it all the way to Super Bowl XX, which they lost against the Chicago Bears 46–10. Following their Super Bowl loss, they returned to the playoffs in 1986, but lost in the first round. The team would not make the playoffs again for eight more years. They changed ownership several times in that period, being purchased from the Sullivan family first by Victor Kiam in 1988, who sold the team to James Orthwein in 1992. Orthwein intended to move the team to his native St. Louis, Missouri, but sold the team two years later to current owner, local businessman Robert Kraft in 1994.
