Editing Super Bowl IX (section)

===Game conditions===
When the NFL awarded Super Bowl IX to New Orleans on April 3, 1973, the game was originally scheduled to be played at the [[Louisiana Superdome]].<ref name=nosfsfsb>{{cite news |url=https://news.google.com/newspapers?id=PphfAAAAIBAJ&sjid=TDEMAAAAIBAJ&pg=3162%2C749555 |work=Lewiston Morning Tribune |location=(Idaho) |agency=Associated Press |title=New Orleans selected for 1975 Super Bowl |date=April 4, 1973 |page=13}}</ref><ref name="argrchs">{{Cite news |date=April 4, 1973 |title=NFL to argue about rule changes soon |url=https://news.google.com/newspapers?id=Em1YAAAAIBAJ&sjid=0fcDAAAAIBAJ&pg=6462%2C3398024 |work=The Bulletin|via=Google News |location=(Bend, Oregon) |page=13 |agency=UPI}}</ref> By July 1974, construction on the dome was not yet finished, and so the league reverted to Tulane Stadium, home field for [[Tulane Green Wave football|Tulane University]] and the [[1974 New Orleans Saints season|New Orleans Saints]], and site of Super Bowls [[Super Bowl IV|IV]] and [[Super Bowl VI|VI]]. Dolphins owner [[Joe Robbie]] lobbied the NFL to move Super Bowl IX to the [[Miami Orange Bowl|Orange Bowl]], already scheduled to host [[Super Bowl X]], and give New Orleans the January 1976 game, but the proposal was rejected.

This proved to be quite pivotal, because of the inclement conditions (low temperature and the field was slick from overnight rain).<ref>{{cite web|url=http://www.steelergridiron.com/history/historyof9.html|title=Super Bowl IX history|url-status=dead|archive-url=https://web.archive.org/web/20070101145937/http://steelergridiron.com/history/historyof9.html|archive-date=January 1, 2007}}</ref>  This was the last Super Bowl to be played in inclement weather for over thirty years, until [[Super Bowl XLI]] (and that game's weather issues in Miami were based on a driving rain, not the temperature). The game still holds the mark as the second-coldest outdoor temperature for an outdoor game, at a game-time temperature of {{convert|46|F}} (only [[Super Bowl VI]], also played at Tulane Stadium, had a colder game-time temperature, {{convert|39|F}}) and expectations that Super Bowl XLVIII would break these records due to its winter location in outdoor New Jersey did not come to pass.  (Seven Super Bowls - [[Super Bowl XVI|XVI]] in Pontiac, [[Super Bowl XXVI|XXVI]] and [[Super Bowl LII|LII]] in Minneapolis, [[Super Bowl XXVIII|XXVIII]] and [[Super Bowl XXXIV|XXXIV]] in Atlanta, [[Super Bowl XL|XL]] in Detroit and [[Super Bowl XLVI|XLVI]] in Indianapolis - have had colder outdoor temperatures but were played in fixed-roof stadiums, except XLVI at the retractable-roofed [[Lucas Oil Stadium]].)<ref name=pfhoftemp>{{cite web |url=http://www.profootballhof.com/news/super-bowl-game-time-temperatures/|title=Super Bowl Game-Time Temperatures |publisher=Pro Football Hall of Fame |access-date=January 30, 2016}}</ref>

The change of venue meant this was not only the last of three Super Bowls played at Tulane Stadium, but the last professional game played in the stadium, which was demolished five years later and replaced for the [[1975 NFL season]] by the [[Louisiana Superdome]], which has hosted every Super Bowl held in New Orleans since.

The circumstances surrounding Super Bowl IX prompted the NFL to adopt a rule prohibiting a new stadium from hosting the Super Bowl following its first regular season. The rule was first invoked in 2018 when construction on [[SoFi Stadium]] for the [[Los Angeles Rams|Rams]] and [[Los Angeles Chargers|Chargers]] in [[Inglewood, California|Ingelwood]], [[California]] fell behind schedule by a year, forcing the NFL to move [[Super Bowl LV]] to Tampa's [[Raymond James Stadium]] and instead playing [[Super Bowl LVI]] at SoFi, which opened for the [[2020 NFL season|2020 season]]. (The first facility to host a Super Bowl in its second season was Miami's [[Hard Rock Stadium|Joe Robbie Stadium]], which opened in [[1987 NFL season|1987]] and hosted [[Super Bowl XXIII]] following the [[1988 NFL season|1988 season]].)
