Antonio Inoki is a wrestling GOD in Japan and regardless of it just being wrestling, in any line of work and life, sometimes you have to really know your role. Great Antonio decided to no sell Inoki and then gave Inoki some stiff shots to an area that is a no-no and that's the back of the neck. Inoki was a bit excessive but it's Japan, looking at the era, it's not that excessive.
Saturn snapped a bit but honestly, if you are a pro wrestler or a long time fan, there's no way you cannot understand why Saturn did what he did. It's not just something wrestlers say but it's the truth; you put your body and life in the hands of someone else and if they cannot perform an arm drag, they should not be wrestling in the ring. Bell messed up two arm drags and both times, Saturn basically landed on his upper back/neck. Saturn didn't go too far compared to what JBL and others have done to jobbers considering the fact Saturn had a legit reason to be upset but even Saturn said he's was a bit out of it.
