How can it be incorrect when I said 'they may'?
Spinning back kicks to the liver? Really? As you are an adherent of the Church of Video you must a video of that because I would really really like to see that. In over 17 years in MMA and 40 in TMA I've see a lot of KO's and TKOs, never seen a 'spinning back kick' do one.
Incorrect again. You said: " They may be able to KO each other quite successfully but outside the gym," --Tex3
This implies that KO's happens somewhat often or even quite often, which I replied that you're wrong, as it only happens very rarely. If you actually have fought full contact, you'd know that it's very difficult to KO someone of similar skill level. And we don't go for the KO on people significantly less experienced and we go very light on all the women, which you should know this part already.
And no videos. I don't go around recording myself in every sparring class as this would be pretty weird.
