The first 4 Super Bowls were the best. The leagues despised each other. Players for the AFL attended the super bowl not to hawk products but to root for the AFL. Vince Lombardi openly mocked the AFL. When the Jets beat the Colts it was the AFL beat the NFL and the Chiefs put the frosting on the cake dominating the Vikings. It was great being a different league right down to using a different football.
I do miss the AFL.
