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.
Oakland Raiders
The rivalry between the Raiders and New England Patriots dates to their time in the AFL, but was intensified during a 1978 preseason game, when Patriots wide receiver Darryl Stingley was permanently paralyzed after a vicious hit delivered by Raiders free safety Jack Tatum. Before that, New England also lost a playoff game in 1976 to the Raiders; the game is unofficially known as "The Ben Dreith Game" due to a controversial penalty by head referee Dreith. While based in Los Angeles, the team hosted New England in the divisional round of the playoffs in 1986. The game was won by New England and marred by a chaotic rumble between the teams in the end zone as players were leaving the field after the game. The brawl was especially notable for Matt Millen attacking Patriots GM Patrick Sullivan with his helmet. The two teams met in a divisional-round playoff game in 2002, which became known as the "Tuck Rule Game". Late in the game, an incomplete pass, ruled a fumble, by Patriots quarterback Tom Brady was overturned, and New England went on to win in overtime and eventually won the Super Bowl against the heavily favored St. Louis Rams, the Raiders' former crosstown rivals in Los Angeles. Since that game, the Patriots have won five of the last six regular season contests between the two teams. The first contest being the following year during the 2002 season in Oakland, with the Raiders winning 27–20; they met in the 2005 season opener in New England with the Patriots ruining Randy Moss' debut as a Raider 30–20; the Patriots defeated the Raiders 49–26 in December 2008 in Bill Belichick's 100th regular season win as Patriots coach; a Patriots 31–19 win during the 2011 season; a scrappy 16–9 Patriots win in the third week of the 2014 season, and the Patriots' 33–8 win in Mexico City in 2017.
