Maybe its just me but I see few guys there that I think could compete at the UFC level and none with any chance of real success. There champs are lower mid tier UFC level good enough to keep employed but the kind of guy who wins one, loses one to mid level talent. I think a guy like Boku would at best be as successful as a guy like Sam Stout, win one lose one repeat.
I think they have a few guys that could do well in the UFC. Guys like ERic Kelly, Roy Docyogen, Bae Young Kwon, Bibiano Fernandes, Eduard Folayang, Masakatsu Ueda, Shinya Aoki would all have good success in the UFC. Boku, Soo Chul Kim would all do okay.
