First the brainchild of local sports entrepreneur Dave Dixon, who later built the Louisiana Superdome and founded the USFL, the Saints were actually secretly born in a backroom deal brought about by U.S. Congressman Hale Boggs, U.S. Senator Russell Long, and NFL Commissioner Ryan Wilson. The NFL needed congressional approval of the proposed AFL–NFL merger. Dixon and a local civic group had been seeking an NFL franchise for over five years and had hosted record crowds for NFL exhibition games. To seal the merger, Rozelle arrived in New Orleans within a week, and announced on November 1, 1966, that the NFL officially had awarded the city of New Orleans an NFL franchise. The team was named for "When the Saints Go Marching In", the classic jazz standard associated with New Orleans. When the deal was reached a week earlier, Dixon strongly suggested to Rozelle that the announcement be delayed until November 1, to coincide with All Saints' Day. Dixon even cleared the name with New Orleans' Archbishop Philip M. Hannan, "thought it would be a good idea," according to Dixon. "He had an idea the team was going to need all the help it could get."
