I submit to you, the NFL is in the perfect position to be usurped by another league. If thirty-two guys got together, I mean rich guys, organized a league, they might be in the right place at the right time.
With the lock-out, players are able to sign with anyone they want, from professional soccer, to the senior dog racing league (Picture it...). If a new league, let's call them the PFL (Professional Football League), formed and offered the players fair contracts, with good profit sharing, and benefits (The new league would not need to address retired players benefits, as they have no retired players), the PFL might (Should) be able to scoop most if not all of the current players.
Now consider this: What if the new league reverted back to some of the old rules? None of this flag football crap. What if they returned the game to what the fans wanted to see? Boom, takeover complete.
The new league could even play the same time of year as the NFL does now. Even if the NFL signed players of inferior caliber to fill their ranks, their game wouldn't compare to that of the new league. This would lead to the Television networks jumping ship and that would lead to the NFL's demise.
To start, the new league would have to play games at university stadiums and the like, but in two or three years, they could purchase some really nice professional quality stadiums for a song.
Think about it.
