I hate to be cynical, but there is precedent for this. Once upon a time the World Wrestling Federation was embarked on national expansion and intended dominance of the market place in 1984-1985. The largest rival promotions of the time (Jim Crockett Promotions (NWA) and Verne Gagne’s AWA) joined forces to create Pro Wrestling USA as a firebreak to the WWF. It presented supercards and had its own television tapings.
However the personalities of Verne Gagne and Jim Crockett could not work together. They were paranoid about each sabotaging the other, and Pro Wrestling USA dissolved within a year. The WWF continued its expansion unabated. Left alone, Jim Crockett became bankrupt three years later through a combination of aggressive WWF business practices and over expanding in an effort to compete. Verne Gagne decided his way was the best way, and saw his talent steadily signed away to the WWF. He was out of business six years after Pro Wrestling USA folded.
That is a possible future of this football alliance. Can the three conferences put aside petty squabbles, past histories, and paranoia to truly work together? If they can’t, all but a handful of these programs will be going away as the remainder will become SEC affiliates.
