I don't think I agree with that. Boxing has dignity; it doesn't need to be cartoonish, with 15 minute ring walks. A fighter should be focusing on the guy he'll be fighting, not shaking his ass like Britney Spears or wearing a Darth Vader mask. If I ever trained a fighter and he expressed a desire to perform some elaborate ring walk, I'd sucker punch him.
Same thing with spectacular kos...It is almost like decision don't count any more, that devising a fight plan, executing it, and sticking to it is wrong unless you 'go for the ko.' Put two good fighters in the ring, guys with class and skill, that hit and don't get it, both of them in there to win, you'll have a good fight and people will watch it.
If the idea is to "improve" boxing by appealing the crowd that only wants blood, gore, flying teeth and 'brutal' kos (which is a part of the thing), then you are heading in the wrong direction and it would be best to just let it die.
