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
The game heralded the Patriots dynasty, being the first of nine Super Bowl appearances under the duo of head coach Bill Belichick and quarterback Tom Brady. The Patriots finished the 2002 NFL season 9-7, missing the playoffs. But they went on to win Super Bowl XXXVIII, Super Bowl XXXIX, thus winning three Super Bowls in four years. Then, they won their fourth and fifth Super Bowls (Super Bowl XLIX and Super Bowl LI) a decade after their third. Brady also won three more Super Bowl MVP awards in Super Bowl XXXVIII, Super Bowl XLIX, and Super Bowl LI, making him the only player to be named Super Bowl MVP four times. Super Bowl XXXVI later became part of the wider 2007 New England Patriots videotaping controversy, also known as "Spygate". In addition to other videotaping allegations, the "Boston Herald" reported, citing an unnamed source, that the Patriots had also taped the Rams' walkthrough practice prior to the game. After further investigations, the league determined that no tape of the Rams' Super Bowl walkthrough was made, and the "Herald" later issued an apology in 2008 for their article about the alleged walkthrough tape. Nevertheless, the Patriots finished the 2007 regular season with a perfect 16–0 record, but failed to record an undefeated 19–0 championship season after losing Super Bowl XLII to the New York Giants. And at the conclusion of the 2015 NFL season, the Patriots held the NFL's best record since Spygate, compiling a 96-32 record from 2008 to 2015.
The Patriots' win in this Super Bowl, beyond just serving as a springboard to four more championships, also became the starting point for a decade of success in Boston sports, with the city's teams winning seven championships in the four major North American sports leagues (the NFL, the NBA, the NHL and MLB), including at least one in each league. Over the next fifteen years, in addition to the Patriots' four additional Super Bowls:
