You can find players, certainly. There will be players in football shape (or reasonably so) when they are asked to leave NFL camps (there's going to be a bit of a lag, obviously, between when they leave camps and when the FXFL can reasonably open camps if they're going to start playing sometime in mid-to-late October).
But between now and then, even IF they've "discussed" venues and IF there's been some media attention (which, let's be honest, has been a few online articles and radio show appearances) and IF some television outfit somewhere is somewhat interested, there are hundreds, if not thousands, of little things that have to be done if you're going to have a football league play in 100 or 110 days.
You have to hire coaches and GMs and people to sell tickets. You have to order equipment and find training sites and print brochures and get phones and internet and a legitimate website and communications people and marketing people and volunteers and logos and insurance and (you'd think) cheerleaders and announcers and officials and chain gangs and sponsors and sports medicine people and a ton of other things.
It's REALLY hard to do all those things in a year, and even if they've been working in stealth mode for the last six months, they'd STILL be behind the eight-ball. And even if they had been working in stealth mode for the last six months, you'd have heard SOMETHING about movement. People would be leaving jobs to go work for them, coaches' agents would be leaking information, you'd see instagrams of uniform concepts, all the things that happen in 2014 that make it really hard to keep secrets.
Now, can you pull together a haphazard thing where you can stage football games that have 22 players and a football? Sure. You can do that. But you have to generate revenue to make it all happen, and it takes time to generate revenue. 100-110 days just aren't enough.
The XFL went from announcement to the field in a year, with, certainly, some groundwork done prior to the announcement.
The UFL had done some mucking about prior to its initial plan to take the field in the fall of 2008, but hadn't really made much headway before announcing in February 2009 that Pelosi was in and they were going to play eight months later. (That ended up being the soft launch season, which could be an option for these guys, but might end up hurting them more than helping them.)
Lastly, drawing inferences that they might be able to pull it off because you think you read something somewhere and might have heard something else somewhere else...well, that leads to a lot of misconceptions.
