Back to the subject at hand. The USFL will flop, and flop in a hurry. It doesn't matter what season the play it in, or how they market it. There's no room for another professional football league. Maybe back in the day when the USFL was first introduced, but not now. The NFL is exponentially more powerful and popular than back in the 80's. College football has moved in as a distant second, but still way more popular now than the USFL ever was. There's just an oversaturation of NFL and college football going on 24/7/365, along with all other sports for that matter. Nobody wants to learn new teams, new names etc.
The only way I see any hope for it, is if it was an NFL feeder system that the NFL itself took under its wing and marketed the hell out of it as if it were an extension of the league. Maybe then. Otherwise, like all others before, over the last few decades, it will look viable for a few weeks before attendance and viewership are both in the tank.
