AFL–NFL merger

[12] The new league had six franchises by August 1959[13] and eight by the time of its first opening day in 1960: Boston Patriots, Buffalo Bills, Titans of New York, Houston Oilers, Denver Broncos, Dallas Texans, Oakland Raiders, and Los Angeles Chargers.

From major colleges, it signed talented players like LSU's Heisman Trophy winner Billy Cannon, Arkansas's Lance Alworth, Notre Dame's Daryle Lamonica, Kansas' John Hadl, Alabama's Joe Namath, and many more.

These included Jack Kemp, Babe Parilli, George Blanda, Ron McDole, Art Powell, John Tracey, Don Maynard, and Len Dawson.

Another example was Dallas Cowboys general manager Tex Schramm, a close friend of Rozelle (Schramm hired Rozelle as Rams' GM), who was influential in NFL coverage by its national TV partner, CBS, including the network's employment of former NFL players as game announcers and the absence of AFL scores and reports on the network.

With a few exceptions, Hunt had successfully recruited owners who not only had deep pockets, but more importantly, the patience and willingness to absorb the inevitable financial losses of the fledgling league's early years.

This unwritten agreement was broken in May 1966, when the NFL's New York Giants signed placekicker Pete Gogolak, who had played out his option in 1965 with the AFL's Buffalo Bills.

Then occupied by Cleveland Browns owner Art Modell, the NFL presidency was (both before and after the merger agreement) essentially an honorary title.

The most notorious example of Rozelle directly intervening in AFL affairs came prior to the 1969 season when he forced Super Bowl III-winning quarterback Joe Namath to divest his stake in a New York nightclub with alleged ties to gambling and organized crime.

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).

The final five proposals were as follows: PLAN 1: East: NYG, PHI, WAS, ATL, MIN; Central: CHI, GB, DET, NO; West: LA, SF, DAL, STL.

PLAN 2: East: NYG, PHI, WAS, MIN; Central: ATL, DAL, NO, STL; West: LA, SF, CHI, GB, DET.

PLAN 3: East: NYG, PHI, WAS, DAL, STL: Central: CHI, GB, DET, MIN; West: LA, SF, ATL, NO.

PLAN 4: East: NYG, PHI, WAS, STL, MIN; Central: CHI, GB, DET, ATL; West: LA, SF, DAL, NO.

PLAN 5: East: NYG, PHI, WAS, DET, MIN; Central: CHI, GB, DAL, STL; West: LA, SF, ATL, NO.

[34] These five combinations were written up on slips of paper, sealed into envelopes and put into a fish bowl[35] (other sources say a flower vase), and the official NFC alignment—Plan 3—was pulled out by Rozelle's secretary, Thelma Elkjer.

Long-time sports writer Jerry Magee of the San Diego Union-Tribune wrote: "Al Davis taking over as commissioner was the strongest thing the AFL ever did.

However, other observers consider those scenarios far-fetched: the NFL had a richer television contract at the time of the merger, in large part because of market exclusivity in such leading population centers as Los Angeles, Chicago, Detroit, Philadelphia, Washington, Baltimore, Atlanta and the Dallas–Fort Worth area, which were rapidly increasing in population and would emerge as media strongholds in the 1970s.

Despite AFL triumphs in Super Bowls III and IV, the old-guard NFL was still widely expected to dominate the merged league over the course of an entire season.

In spite of Rozelle's promise that there would be no re-locations involving teams in existence at the time of the merger, by the end of his tenure as commissioner in 1989 three franchises had moved to a different market from where they were based in 1970.

AFL and NFL teams at the time of the 1970 merger. Following the merger, all ten former AFL teams as well as Pittsburgh, Cleveland, and Baltimore from the pre-merger NFL joined the AFC. All thirteen remaining NFL teams joined the NFC.
