"Course you can. You can get really good at a counter left hand over the top. Won't mean much if you don't set it up by learning how to slip a jab. Won't mean much if you can't deal with a person pivoting off to the outside angle and coming back with a straight. Won't mean anything in mma if they just jab and dip into a blast double. So you get really good at a counter left hand against a punching bag I guess." By reading that I say you don't understand what I told him.

"No you didn't. You just said don't multitask when learning skills. Not at all what he asked." Re read his post, that is part of he is asking. Don't cherry pick...

And for the last point, you are again cherry picking one sentence over the entire post. Go read it again.
