What sucks is that we may not know whether or not these stoppages were too late until 10 or 20 years down the road. My impression at this point however, is that MMMA competition is indeed the most tightly and best regulated of all combat sports, by a very noticeable margin.
The good news is that guys who have been in serious battles, guys like Couture and Liddell, and Rich himself, seem not only to be doing ok, but are sharp as tacks. With the exception of Liddell perhaps, whose indulgence in drugs of every kind is well documented, and is a major complicating factor.
Having said that, there's really no need to keep pushing the envelope the way that officials like Azzagatti, Yamasaki and Herb Dean all have, to a greater or lesser degree.
And yeah, a 'W' and the extra G's this affords a fighter are important. But there's nothing more important than long term health. MMA's track record given the circumstances is outstanding. Let's keep it that way.
