Joe made a good point in the thread about sparring hard i.e. admitting a student beat you. Rather than hi-jack the thread I was curious as to how many instructors here train their students to beat them?
My goal has always been to produce students who can kick my a**. (hasn't happened yet but that's my goal

) I figure if I can do that and, more importantly, instill in them the same philosophy the style/system will always continue to grow stronger.
The style I trained in years ago had 15th generation black belts. If you figure the head honcho was brilliant but his number two man wasn't quite as good and work that to its logical conclusion the 15th generation guys are going to be pathetic in comparison to the head man.
Train the other way and imagine how good those 15th generation guys are going to be?
I'm wondering if that is why some styles end up disappearing? They get so diluted that they're just not worth learning any more.
Unfortunately I think egos get in the way and/or fear. The instructor thinks that if the guy can beat me why is he going to come to class anymore? I've always been comforted by the fact that boxers figured out long ago you can have the knowledge to teach without being able to beat up on the guy your teaching. I forget the exact age of Ali's trainer back in his glory days but if memory serves it was Angelo Dundee and he was pushing seventy.
Interested in other instructors thought's on this.
