The team was originally slated to be based in Toronto, Canada, with the nickname of the Northmen. However, when Canadian Prime MinisterPierre Trudeau announced that no U.S.-based professional football league would be allowed in Canada in competition with the Canadian Football League under the Canadian Football Act, a change in venue and nickname was announced. From the beginning, Memphians disliked "Southmen" and the team was informally known as the Memphis Grizzlies. The name appeared to come from the logo, a representation of a bear backed by the sun. The "Grizzlies" were owned by John F. Bassett. A multi-millionaire, Bassett gave the league instant credibility by signing three stars from the National Football League's Miami Dolphins for the 1975 season: running backsLarry Csonka and Jim Kiick, and wide receiverPaul Warfield. John McVay was introduced as the head coach before the 1974 season. The Southmen's home opener against Detroit drew 30,122 fans, including Elvis Presley, a professed football fanatic. Country superstar Charlie Rich sang the national anthem. After Rich took his seat next to Elvis afterward, Presley commented, "That's a tough song to sing, ain't it?" Rich replied, "It ain't no Behind Closed Doors." Even before the Miami Trio arrived, the 1974 Southmen found two durable running backs in J.J. Jennings and John Harvey, and they finished with the league's best record at 17–3. They lost in the semi-finals to the Orlando-based Florida Blazers, 18–15. In 1975, Csonka, Kiick, and Warfield finally came to Memphis, but even they couldn't save the league, which folded during the middle of its second season. The 1975 Grizzlies finished 7–4; in their last WFL game, they were shut out by the Birmingham Vulcans, 21–0. Memphis eventually not only received another professional sports team via a relocation from Canada, but one that was officially called the Grizzlies - the Vancouver Grizzlies of the National Basketball Association would move to Memphis in 2001. The NBA Grizzlies are the only major professional sports team to keep its nickname after moving from Canada to the United States. In 2004 Mississippi's Johnny Wofford produced a DVD honouring the 1974–75 Southmen/Grizzlies. It included pictures from the 2004 30 year reunion conference.
The Southmen were one of the stronger and better-supported WFL franchises, and would have almost certainly been a viable venture had the WFL's overall management been more financially sound. After the WFL folded, Bassett applied for membership in the NFL as an expansion team. Over 40,000 deposits for season tickets were collected in this effort, which included a telethon on a Memphis television station, during December 1975. To their dismay, the NFL refused to accept the team. McVay and many of the Southmen moved on to join the New York Giants, where in what has been described as "the closest approximation to a meeting between the champions of the WFL and the NFL", the Southmen reinforcements helped the Giants defeat the defending Super Bowl championPittsburgh Steelers 17–0 in a 1976 preseason matchup. Still, there were fans who would not quit. A lawsuit, Mid-South Grizzlies v. NFL, tried to force the league to accept the Grizzlies. It was not settled until 1984, by which time Bassett owned the Tampa Bay Bandits of the United States Football League and the case was rendered moot. Long after Presley's death in the early 1990s, his estate was involved in an attempt to bring the NFL to Memphis; the Memphis Hound Dogs proposal ultimately lost. The NFL's Tennessee Oilers played their 1997 season in Memphis before making their permanent home in Nashville.
