In this day and age tournament style MMA doesn't work in organizations like UFC with all the time they need between fights for the established names. But with these mid level guys who've outgrown the local circuits of fighting but still trying to attain some name status to get a bunch of fights in quick succession against other quality fighters.
Ben Askren the Welterweight champ of Bellator was a 2 time NCAA wrestling champ and Olympic wrestling competitor in 2008. Hector Lombard is by far the best Middleweight fighter not signed to UFC right now.
Say what you will about Bellator but they deliver exciting events pretty much every time out. There's always contenders for submission of the year or fight of the year coming taking place in Bellator.
