I find it weird how many people are completely ignoring those vicious shots to the back of the head and simply saying "good stoppage."
It seems after this, every fighter out there, after they rock their opponent, should just wail away on the back of their head to end the fight. The ref isn't going to give a shit because it looks like he is protecting the fighter and the winner will be able to dismiss it as the rush of finishing the fight.
In case you havent noticed there are several fights that end with shots to the back of the head in a tko scramble. When there is a tko scrable lots of rules like this are thrown out the window. Fedor doesn't get any special treatment.
