World Series of Fighting just held its second event, and has the MMA world buzzing. WSOF 2 saw a ton of former UFC fighters, like Andrei Arlovski, Anthony Johnson, Josh Burkman, Aaron Simpson, Waylon Lowe, and Kris McCray. Although it is a fledgling federation, MMA fans and pundits are wondering a couple things — will it establish a belt system, and if so, when? Also, will be known as the organization where all the UFC cast-offs go? I think they should have belts, but something like that needs to take time. Also, many of the fighters that have left the UFC may find a home at WSOF and already have established fan-followings.
