<P> Eventually, Congress passed the new law to permit the merger to proceed . The terms of the merger called for the NFL and AFL to add one team each prior to the 1970 season . Louisiana Representative Hale Boggs and Senator Russell Long were instrumental in passage of the new law, and in return, Rozelle approved creation of the expansion New Orleans Saints franchise less than one month after the bill was signed into law by President Lyndon B. Johnson . </P> <P> The tenth and final AFL franchise was awarded to former Cleveland Browns owner and coach Paul Brown in Cincinnati . Brown had been seeking a way back into the NFL after being forced out of the Browns organization by Modell . Brown had not been a supporter of the AFL prior to the merger announcement, but quickly realized the AFL was probably his only viable path back into NFL after the older league awarded its sixteenth franchise to New Orleans . Also, Cincinnati was not going to have a 50,000 seat stadium ready until 1970 . Brown paid $10 million for his franchise (400 times the 1960 franchise fee of $25,000), famously stating "I didn't pay ten million dollars to be in the AFL ." </P> <P> As 1970 approached, three NFL teams (the Baltimore Colts, Cleveland Browns, and Pittsburgh Steelers), agreed to join the ten AFL teams (the Cincinnati Bengals and Miami Dolphins had joined the original Boston Patriots, Buffalo Bills, Denver Broncos, Houston Oilers, Kansas City Chiefs, New York Jets, Oakland Raiders, and San Diego Chargers) to form the American Football Conference (AFC). The other thirteen NFL teams (Atlanta Falcons, Chicago Bears, Dallas Cowboys, Detroit Lions, Green Bay Packers, Los Angeles Rams, Minnesota Vikings, New Orleans Saints, New York Giants, Philadelphia Eagles, St. Louis Cardinals, San Francisco 49ers and Washington Redskins) became part of the National Football Conference (NFC). Since then, the Super Bowl has featured the champions of the AFC and NFC . Both are determined each season by the league's playoff tournament . </P> <P> Although the AFC teams quickly decided on a divisional alignment, the 13 NFC owners had trouble deciding which teams would play in which divisions . The NFL had recently gone to four divisions of four teams each in 1967 . Many NFC teams were attempting to avoid placement in a division with the Cowboys and / or the Vikings, and were trying to angle their way into the same division as the Saints, the weakest team in professional football at the time . The 49ers and Rams, both in California, were guaranteed to be in the same division as the only NFC teams west of the Rocky Mountains . One early proposal would have put the two California teams together with the three Northeast teams--the New York Giants, Philadelphia Eagles and Washington Redskins--reminiscent of the Western Conference's Coastal Division which had put L.A. and S.F. together with Baltimore and Atlanta from 1967--1969 . The final five proposals were as follows: </P>
