Here I go with another poorly digested ramble. I was talking to some older high ranking martial artists and it occurred to me that a couple of these individuals reached their high level black-belt ranks through years of practice, teaching and accumulating knowledge and through dedicated service to their associations, but not buy being especially good at fighting. In fact the best fighters I know are mostly at least 30 years younger than these guys, have a lot of fighting experience but do not have especially high ranks in whatever arts they've trained. On the other hand, of course there are older high ranking individuals who are awesome fighters. My question is this, "How common is it to find older, high ranking (3rd, 4th, 5th degree or higher) black-belts who may really know their stuff, but are not particularly good fighters?" and, "Does this even matter?"
