Three letters for anyone who actually think this would work...
XFL
Never heard of it? Not surprised.

Two of the most successful business men of this era, Vince McMahon and Ted Turner, with all the resources of two multi billion dollar companies, WWE and Time Warner couldn't get a new professional league off the ground.
They had the stadiums, had the TV deals. They tried everything to poach players from the NFL. How many crossed over? None.
Why? These guys have 10 odd years to make their money, the money that has to fund the rest of their lives. You think players are gonna give up guarenteed money and take a risk on a new start up league, wake up.
The sheer amount of money need to start a professional league is absurd. Vince McMahon (multi billionaire, not like these multi millionaires) reportedly lost half his net worth in the venture.
And you really think these players are going to put up their money to do it?
