Assuming the 1960 season kicks off the expansion Dallas Texans and Houston Oilers, this averts a LOT.
The most obvious is the Foolish Club; instead, you probably see the likes of Billy Sullivan in Boston, Ralph Wilson in Buffalo, Max Winter in Minnesota, Bob Howsam in Denver, Barron Hilton in Los Angeles, Rankin Smith in Atlanta and Joe Robbie in Miami bid on the next two teams. Harry Wismer in NYC will try, but if he doesn’t have his shit together, another NYC team will have to wait.
The NFL badly wanted Atlanta in 1966, so it’s hard to imagine they don’t become the 15th team. For the next one, the obvious contenders would be NYC, Miami, New Orleans and Minnesota, and the winner is...probably Miami.
This puts a LOT of potential team owners on the outside looking in - by my count, that’s six owners out in the cold, plus a pissed-off Paul Brown and a possibility of a team in New Orleans.
People who are shut out of the NFL decide to form an alternative league, one that, with time and more interest, forms into something more ambitious than OTL. Instead of eight teams, you have 12 teams, sorted into an East, Central and West division. Also, unlike in the NFL, teams can get into the playoffs by finishing second as a wild card - the best non-division winner plays in the semifinal.
The teams and their respective owners:
EAST
Boston Patriots (Billy Sullivan)
Buffalo Bills (Ralph Wilson)
Cincinnati Bengals (Paul Brown)
New York Knights (Sonny Werblin)
CENTRAL
Chicago Fire (John Allyn)
Dallas Cowboys (Clint Murcheson)
Minnesota Vikings (Max Winter)
New Orleans Saints (John W. Mecom Jr.)
WEST
Denver Broncos (Bob Howsam)
Hawaiians (Christopher Hemmeter)
Los Angeles Chargers (Barron Hilton)
San Diego Storm (C. Arnholt Smith)
The ambitious AFL sticks it out in a lot of cities, but it gets run out of LA (Hilton moves the team to Seattle,) Dallas (in a reversal of OTL, Murchison moves the team to Kansas City and keeps the name,) and Chicago (Allyn sells to investors in Orlando and the team is called the Thunder.)
The AFL negotiates for a merger, but the NFL is wary. Lamar Hunt is on board, as are the recent owners, but there are concerns of franchise stability, particularly in Orlando, Cincinnati and Honolulu. The NFL offers a merger without those teams and with cutting a fourth team of the AFL’s choice; the AFL wants all 12 teams admitted.
Eventually the NFL settles on a plan - Orlando is folded and replaced with an expansion team with a new owner - Bart Starr and Co. - in Phoenix. The other 11 are admitted free and clear, and two NFL teams make the leap to the AFC - let’s go with Baltimore and Atlanta. This leads to an alignment that looks like this:
EAST
Baltimore Colts
Boston Patriots
Buffalo Bills
Cincinnati Bengals
New York Knights
CENTRAL
Atlanta Falcons
Kansas City Cowboys
Minnesota Vikings
New Orleans Saints
WEST
Arizona Firebirds
Denver Broncos
Honolulu Hawaiians
Seattle Chargers
San Diego Storm
EAST
Miami Dolphins
New York Giants
Philadelphia Eagles
Washington Redskins
CENTRAL
Chicago Bears
Cleveland Browns
Detroit Lions
Green Bay Packers
Pittsburgh Steelers
WEST
Dallas Texans
Houston Oilers
Los Angeles Rams
St. Louis Cardinals
San Francisco 49ers
