To say that "if he was good they would have kept him around" is just silly.
They let MacDonald, Mousasi, Krylov, Horiguchi and many others go, because they couldn't dig in their pockets. I agree that Tumenov is not some world-beater, but he's still a pretty solid win because nobody ever saw Edwards winning that fight.
Also, lol @ your haterade. "I didn't see him knock him down because I was too busy falling asleep", mate, the knockdown was in Round 1? Why on earth were you falling asleep in Round 1?
