Show me an instance where this has happened in BJJ or how this could possibly have a negative affect on a BJJ fight. I have never seen it happen. Maybe you are more privy to dirty wrestling in BJJ matches than I am. I watch most high level televised grappling, and I haven't seen it.
Show me any other wrestlers who have used it for 5 rounds with gray area tactics outside of typical smothering ala dirty wrestling. I really don't think you watch much MMA because you don't seem to understand how the Anderson fight is in a league of its own here, judging from your argument. So I have to ask, did you watch the Anderson fight? Did you watch it online? There is a big difference and its possible you missed some aspects of the fight.
Can you demonstrate that these tactics are "normal" and therefore sportsmanlike in BJJ comps?
In MMA, its only happened a handful of times in a decade. Both times the 2 wrestlers who have abused it went too far with it to the point it put a cloud over the fight. I love and respect one of them after it because he owned it, he said hey guess what I'm about that action, I'll do whatever I can to win in a fight. The other one is a liar and spammed the MMA news sites with how much he respects Anderson.
Otherwise, agree to disagree. You are entitled to your perspective.
