For those that haven't seen the fight, this is why people are claiming it as a fix. Chael fell back looking for the guillotine just after this (like he did against Shogun), Tito passed to half guard, popped his head out, got to mount and it was over very quickly after that.
Yep. Have checked out a few videos. Nothing in it. Yeah Chael put in a s**t effort but there is no way it was fixed. Makes no sense
