They can't put competent teams on the field. The talent for it doesn't exist.
Again, this league, USFL, XFL, UFL, whatever they want to call it, was doomed from the get go because it doesn't have NFL backing as a developmental league. Going on their own with an entire league that is nothing but last preseason game 4th string football, nobody wants to see that, and more importantly nobody wants to pay to see it.
Even with the TV contracts they have, this league won't last very much longer because if the stands are empty, I can't image TV ratings are too much higher than 0. No eyeballs means no one is seeing ads. Game over.
And I can't imagine another go at something like this unless the NFL is involved somehow. Its just not going to work without them. And the way the NFL tries to squeeze every nickel they can get, I seriously doubt they'll ever put money into something that they won't get a big return on. I mean, they actually tried it once with NFL Europe and pulled the plug on it because it wasn't profitable. This may be the last we see of these little spring leagues.
