He was supposed to be in the ufc around the time he took those fights actually. The promotion wouldn't release him and he spent a long time fighting them in court. Would've been nice to Khabib in the ufc in 2010. I think people shit on his early resume too much. Not everyone is lucky enough to get picked up by the ufc early in their career like GSP, BJ and Jones. You gotta fight whoever you can.
But for what it is worth I do think people overlook is that in that scene there wasn't a huge pool of experience pros compete against. They did however have TONS of amateurs, sambo guys, kickboxers, grapplers, etc that competed in those promotions. So those recordsvare often deceptive. Even Khabib has unaccounted for amateur mma fights.
