Watch out Yahoo and ESPN (and even FleaFlicker!), there's another fantasy football league website in town, this one having the unique concept of being built into Facebook. Jeff Ma, one of the MIT card counters that inspired the book Bringing Down the House (which is a great book by the way) and the movie "21", along with business partner Mike Kerns, have created the company Citizen Sports, Inc., and convinced Sports Illustrated to put its name on the product. The fact that it is a downloadable application on the new Facebook means it will automatically have a potential audience of millions, so there is a big chance that this could succeed...but we'll have to wait and see if it really challenges the big boys any time soon. (More, including a couple screenshots, after the jump...)

You can find the league add-on for Facebook here if you're interested. Just for kicks, I've signed up for a public league, with an autodraft of August 22nd, just to see how the site works. I'll keep everyone posted with my thoughts and experiences as the season approaches. Below you can see an example that Facebook shows for what your team view will look like when the season starts. I'm already excited to send out my first "Can of Smack"!
