I've also agreed with you in that sparring hard in training is important. However, Hard Sparring does not need to be to a KO. This is where we seem to disagree.
"Hard Sparring", varies from gym to gym. Hard sparring to you, probably only means medium sparring to me and most Boxing gyms....where hard sparring means throwing punches up to 100% power. Regular sparring to us, usually means up to 70% power, but it often spikes to 100% power when someone gets mad. But at 70% power, it still hurts and you still can get KO'ed if you get caught. That's why I like to say, sparring for KO, in order to not be ambiguous as lots of gyms have various definitions.
Do KOs happen? Yes. I even wrote in post #21; "can it happen, does it happen? Yes." (you may have missed that)
So we disagree and that means I've never trained hard, sparred hard, nor am I well trained. Ok.
Sorry about this hysterical rant.
We disagree on what "hard sparring" means. That's why I like to say, "sparring for KO", which makes it crystal clear. The first time I went to that gym in my first video up top for sparring class, I asked the Coach "how hard are we going?"....He said, just "pace yourself, this kid is a fighter, he can take it"......I was like WTF does that mean (inside my head)? Bell rings, and this kid, a fighter....whacks me with a full overhand right so hard that I start seeing stars. So I put him down. No problem w/the Coach at all...but see how ambiguous this is if I were to come to your gym and you said "hard sparring"? To me, that would mean your guy(s) will be trying to KO me so I better get them first.
Oh and yes, I believe I have heard of Muhammad Ali a time or two.
Well then, by your arguments, he shouldn't be having all of his "neurological disorders", yes?
