Just a few fighters @ LHW are good enough to be considered top players, with a chance of getting to a title fight.
DC, Gus, Volkan, Teixeira and Manuwa.
The rest of the "top 15" beat each other left and right, and are way below these guys in technique and the all-around game.
I hope Cirkunov and Antigulov can make things happen, but it's doubtful.
