Question: When was the last time the team that played the Packers in Super Bowl I went to the superbowl?

full_context: Document 1: Super Bowl: The leagues' owners chose the name ``AFL -- NFL Championship Game '', but in July 1966 the Kansas City Star quoted Hunt in discussing`` the Super Bowl -- that's my term for the championship game between the two leagues'', and the media immediately began using the term. Although the league stated in 1967 that ``not many people like it '', asking for suggestions and considering alternatives such as`` Merger Bowl'' and ``The Game '', the Associated Press reported that`` Super Bowl'' ``grew and grew and grew - until it reached the point that there was Super Week, Super Sunday, Super Teams, Super Players, ad infinitum ''.`` Super Bowl'' became official beginning with the third annual game. Roman numerals were first affixed for the fifth edition, in January 1971.
Document 2: Super Bowl LII: Super Bowl LII was an American football game played to determine the champion of the National Football League (NFL) for the 2017 season. The National Football Conference (NFC) champion Philadelphia Eagles defeated the American Football Conference (AFC) and defending Super Bowl LI champion New England Patriots, 41 -- 33, to win their first Super Bowl and their first NFL title since 1960. The game was played on February 4, 2018, at U.S. Bank Stadium in Minneapolis, Minnesota. This was the second time that a Super Bowl was played in Minneapolis, the northernmost city to ever host the event, after Super Bowl XXVI at the Metrodome during the 1991 season, and the sixth Super Bowl held in a cold - weather city.
Document 3: Super Bowl XXXVI: Super Bowl XXXVI was an American football game between the National Football Conference (NFC) champion St. Louis Rams and the American Football Conference (AFC) champion New England Patriots to decide the National Football League (NFL) champion for the 2001 season. The Patriots defeated the Rams by the score of 20 -- 17. It was New England's first Super Bowl championship, and the franchise's first league championship of any kind, having suffered two previous losses. The game was also notable for snapping the AFC East's long streak of not being able to win a Super Bowl championship, as the division's teams had lost eight Super Bowls in total (prior to the Patriots victory in XXXVI).
Document 4: Super Bowl XLV: Super Bowl XLV was an American football game between the American Football Conference (AFC) champion Pittsburgh Steelers and the National Football Conference (NFC) champion Green Bay Packers to decide the National Football League (NFL) champion for the 2010 season. The Packers defeated the Steelers by the score of 31 -- 25.

Document 5: 1969 Kansas City Chiefs season: The 1969 Kansas City Chiefs season was the team's 10th, their 7th in Kansas City, and also their final season in the American Football League. It resulted in an 11 -- 3 record and a 23 -- 7 victory in Super Bowl IV over the NFL's heavily favored Minnesota Vikings. The team beat their rivals, the Oakland Raiders in the final AFL Championship Game, claiming their third AFL Championship in franchise history. The Chiefs were coached by Hank Stram, led by quarterback Len Dawson and a powerful defense led by Bobby Bell, Willie ``Contact ''Lanier, Buck Buchanan and Curley Culp.

The team's victory on January 11, 1970, remains the club's last championship game victory and appearance to date, and occurred in the final such competition prior to the leagues' merger coming into full effect. The Chiefs were also the second team, after the Green Bay Packers, to appear in more than one Super Bowl (the first AFL team to do so) and the first to appear in the championship game in two different decades.
Document 7: Green Bay Packers: The Packers have won 13 league championships, the most in NFL history, with nine pre-Super Bowl NFL titles in addition to four Super Bowl victories.

Document 9: Super Bowl I: After both teams traded punts on their first possessions of the game, the Packers jumped out to an early 7 -- 0 lead, driving 80 yards in six plays. The drive was highlighted by Starr's passes, to Marv Fleming for 11, to Elijah Pitts for 22 yards on a scramble, and to Carroll Dale for 12 yards. On the last play, Bart Starr threw a pass to reserve receiver Max McGee, who had replaced re-injured starter Boyd Dowler earlier in the drive. (Dowler had injured the shoulder the previous week after scoring a third quarter touchdown; Cowboys defensive back Mike Gaechter had upended him several steps after scoring and he landed awkwardly.) McGee slipped past Chiefs cornerback Willie Mitchell, made a one - handed catch at the 23 - yard line, and then took off for a 37 - yard touchdown reception (McGee had also caught a touchdown pass after replacing an injured Dowler in the NFL championship game). On their ensuing drive, the Chiefs moved the ball to Green Bay's 33 - yard line, but kicker Mike Mercer missed a 40 - yard field goal.
Document 10: Kansas City Chiefs: The Chiefs have won three AFL championships, in 1962, 1966, and 1969 and became the second AFL team (after the New York Jets) to defeat an NFL team in an AFL -- NFL World Championship Game, when they defeated the Minnesota Vikings in Super Bowl IV. The team's victory on January 11, 1970, remains the club's last championship game victory and appearance to date, and occurred in the final such competition prior to the leagues' merger coming into full effect. The Chiefs were also the second team, after the Green Bay Packers, to appear in more than one Super Bowl (and the first AFL team to do so) and the first to appear in the championship game in two different decades.
Document 11: Green Bay Packers: The Packers have won 13 league championships, the most in NFL history, with nine pre-Super Bowl NFL titles in addition to four Super Bowl victories. The Packers won the first two Super Bowls in 1967 and 1968 and were the only NFL team to defeat the American Football League (AFL) prior to the AFL -- NFL merger. The Vince Lombardi Trophy is named after the Packers' coach Lombardi, who guided them to their first two Super Bowls. Their two additional Super Bowl wins came in 1997 and 2011.
Document 12: History of the National Football League championship: From 1966 -- 1969 prior to the merger in 1970, the NFL and the AFL agreed to hold an ultimate championship game, first called the AFL - NFL World Championship Game and later renamed the Super Bowl after 1968. Following the merger in 1970, the Super Bowl name continued as the game to determine the NFL champion. The most important factor of the merger was that all ten AFL teams joined the NFL in 1970 and every AFL championship game and record is included in NFL record books. The old NFL Championship Game became the NFC Championship Game, while the old AFL Championship Game became the AFC Championship Game. The NFL lists the old AFL / NFL championship games with ``new ''AFC / NFC championship games in its record books. The Green Bay Packers have won the most championships with 13 total (9 NFL championships pre-merger, four (4) Super Bowl championships). The Packers are also the only team to win three consecutive championships, having done so twice (1929 -- 1931, 1965 -- 1967). The Chicago Bears have won the second most overall championships with nine (9) (eight NFL championships, one Super Bowl championship).

Document 14: Super Bowl I: The first AFL - NFL World Championship Game in professional American football, known retroactively as Super Bowl I and referred to in some contemporaneous reports, including the game's radio broadcast, as the Super Bowl, was played on January 15, 1967 at the Los Angeles Memorial Coliseum in Los Angeles, California. The National Football League (NFL) champion Green Bay Packers defeated the American Football League (AFL) champion Kansas City Chiefs by the score of 35 -- 10.
Document 15: List of Super Bowl champions: Before the 1970 merger between the American Football League (AFL) and the National Football League (NFL), the two leagues met in four such contests. The first two were marketed as the ``AFL -- NFL World Championship Game '', but were also casually referred to as`` the Super Bowl game'' during the television broadcast. Super Bowl III in January 1969 was the first such game that carried the ``Super Bowl ''moniker in official marketing, the names`` Super Bowl I'' and ``Super Bowl II ''were retroactively applied to the first two games. The NFC / NFL leads in Super Bowl wins with 26, while the AFC / AFL has won 25. Nineteen different franchises, including teams that relocated to another city, have won the Super Bowl.
