 Tampa Bay, Jacksonville, Birmingham and Memphis were consistently among the league's leaders in attendance, mainly because none of those cities had to compete against Major League Baseball teams for the spring sports dollar.Of those cities, only Tampa Bay now has a baseball team; the Rays, formerly known as the Devil Rays, didn't arrive until 1998.Along with Philadelphia/Baltimore (the league's most successful team, and one that was about to step into a recently abandoned NFL market) and New Jersey (with Trump's deep pockets, the league's greatest player in Walker, strong attendance, and distance from New York's MLB teams), this collection of teams were widely reckoned as at least having the potential to be viable ventures had the USFL stuck to its original springtime concept and been more financially sound.
