Why that specific spinning elbow landed(esp. so cleanly). The setup.

[Bull Terrier]

conventional boxing doesn't seem to mean much when you're getting elbowed in the face and kicked in the knee cap.

Those elbows are vicious as hell, but I was kind of surprised at just how bad Jones' hands are.

You should watch the vid. of Big John's meeting with the fighters going over all of the rules.

When your opponent is turning their head as you are throwing the strike then you given some leeway if it accidentally hits an illegal zone though subsequent strikes will be issued a warning and if it incapacitates then it may lead to a DQ or NC.

As soon as Jon beings to spin Bonnar lowers his head and brings it more forward. Both contributed to where it ultimately struck though neither was "at fault".
