The Tag Team Division is super important however Vince wants instant gratification and he's trying to make a superstar overnight. There is nothing wrong with partners just being thrown together or forming naturally.
Look back and look at some of the great single wrestlers who were stuck in tag teams for the start of their career; The Rockers, Hennig & Hall, Hart Foundations, Beer Money, The Dudleys, Edge & Christian, The Hardys, Harleem Heat, The Stiener Brothers, The Bulldogs, The Freebirds, Miz & Morrosin, Hawkins & Ryder, the Hollywood Blondes.
It didn't matter if they formed naturally or were thrown together by a promoter. The only thing that mattered was they got on TV and won titles which built a foundation for future success.
